Replacing spark plugs on a Lada Granta (16 valves) with your own hands

A malfunction of the spark plugs immediately affects the operation of the engine; it begins to stall, jerk, does not pull, or starts poorly. To solve the problem, simply replace them with new ones, but which spark plugs are better to choose?

All modern 8 and 16 valve power units have the same manufacturer's recommendation. In other words, advice on choosing spark plugs will be similar for all modern Lada cars.

In the user manual for Lada Priora, Kalina, Granta, Vesta Largus, Niva and XRAY cars, the engine technical specifications contain the following data:

The gap between the spark plug electrodes should be within 1...1.15 mm. Let us remind you that Lada Vesta and Lada XRAY can be equipped with a Nissan-Renault HR16/H4M engine. The spark plug gap in this case should be 0.85...0.95 mm. For K4M/K7M engines (more about spark plugs), the gap between the spark plug electrodes is 0.95+-0.05.

According to the requirements, the manufacturer must guarantee uninterrupted operation of the spark plugs for 18 months, provided that the vehicle mileage does not exceed 20,000 km. However, with good technical condition of the engine and proper operation, the service life of the spark plugs can be significantly longer. Thus, spark plugs are often replaced every 3 years or after 40 thousand km.

Marketers suggest improving engine performance by installing, for example, iridium, platinum or multi-electrode spark plugs on the Priora, the price of which is higher than usual. AVTOVAZ recommends using conventional, single-electrode spark plugs for its engines. In a review by ZaRulem magazine, a survey was conducted that shows that the majority of drivers follow the factory’s recommendations and choose simple, inexpensive spark plugs.

As part of the same review, nine different spark plugs were tested. As a result, they all passed the tests, and the winner was determined by summing up the points:

So what spark plugs should I put on Priora/Granta/Kalina/Vesta? Based on the recommendations of AVTOVAZ, the test results of a popular car magazine and a survey of the social network VKontakte, we can conclude that the best choice would be spark plugs from manufacturers: NGK, Bosch, Denso, Brisk and EZ Standard.

The Lada Granta engine with 8 valves is simple, so when replacing spark plugs, you should not spend money on consumables with iridium or platinum electrodes - the result expected from such a replacement will only be on new 16-valve internal combustion engines. Ordinary and inexpensive ones with an average heat rating are sufficient. Cold spark plugs (20 and above) often miss a spark, and at idle the engine will be completely unstable, and so-called. “hot” ones will “harass” the owner with detonation after turning off the ignition.

Below we have selected, in our opinion, the best options for replacing the Lada Granta. User opinions indirectly confirm that it is difficult to find better spark plugs for the Lada Granta.

Spark plugs for Lada Granta: which ones to choose and how to change them

Before replacing spark plugs on a Lada Granta, you need to know some features of choosing new parts. For internal combustion engines with 8 valves, the manufacturer recommends installing spark plugs SZ A17DVRM or A15DVRM. For internal combustion engines with 16 valves, it is recommended to install spark plugs AU17DVRM or AU15DVRM.

If these spark plugs do not quite suit the car owner according to some criteria, you can choose an analogue:

• spark plugs for Grant 8 valves - Beru 14R-7DU, Champion RN9YC, NGK BPR6ES, DENSO W20EPR.
• spark plugs for Granta 16 valves - Beru 14FR-7DU, Champion RC9YC, NGK BCRP6ES, Denso Q20PR-U11.

Having selected spark plugs for the Lada Grant, you also need to take into account the features of replacing spark plugs on Grant cars with 8 and 16 valve internal combustion engines. Replacing the spark plugs itself is a fairly simple procedure, but there are some nuances. However, using the installation instructions and having the tools, it is quite possible to carry out the replacement yourself.

Replacing Grant spark plugs:

• Having de-energized the on-board network on the 16-valve internal combustion engine, we remove the cover (there is no cover on the 8-valve engine);
• in the case of a 16-valve engine, press the latch to turn off the ignition coil block (each spark plug has its own coil); in the case of an 8-valve engine, we skip this point;
• Using an asterisk we unscrew the screws that secure the mounting locations of the coils for their subsequent dismantling;
• for an 8-valve engine, we disconnect the high-voltage wires from the short circuit, remembering which wire goes to which spark plug;
• depending on the specification of the internal combustion engine, use a key set to “21” or “16” to dismantle the faulty spark plugs and install new ones;
• in the case of a 16-valve internal combustion engine, do not forget about installing and connecting the coil;
• in the case of an 8-valve engine, new spark plugs must be installed and tightened by hand, and then tightened with a wrench;
• Reinstall the high-voltage wires in the order in which they were originally.

Rating of the best spark plugs

When forming the rating, we took into account the characteristics of spark plugs. As a result, our TOP includes only the best models that are optimally suited specifically for the Lada Granta vehicle. In addition, we took into account the opinions of users. For this reason, our rating includes only those spark plugs that received the largest number of positive reviews from car owners.

The best SZ from famous manufacturers

Here are the best spark plugs from well-known manufacturers.

No. 5. DENSO 4604 K20TT

These are inexpensive and high-quality spark plugs.
The products are equipped with a thin electrode that promotes rapid ignition. Thanks to this, the motor runs smoothly, the engine starts faster and its vibration is reduced. DENSO 4604 K20TT
Specifications:

main electrode size – 1.5 mm; number of side electrodes – 1; motor type – petrol; tightening angle – 90 degrees.

Pros: high quality; reliable manufacturer; affordable cost; positive effect on engine performance; long period of action.

VAZ-21126 and 21127 engines are equipped with 16 valves, but the spark plugs in them need to be changed as often as in 8-valve engines. The replacement interval is 30 thousand km. The spark plug wells will be covered by the ignition coils. Therefore, first disconnect the coil connector, unscrew it, and then you can unscrew the spark plug. During installation, it is better to use a ratchet wrench, withstanding a force of 25–30 N*m.

Established rules for replacing spark plugs on a Lada Vesta car

Scheduled maintenance on the 2180 includes replacement of igniters. The operating regulations for classic devices indicate the following update frequency: every 30 thousand km (15 thousand km with high mileage). And iridium and platinum ones need to be updated every 100 thousand km.

In addition, the condition of the engine may indicate the need for urgent replacement. If cracks appear on the ceramic part or the insulator has peeled off from the metal part, then it is time to replace the entire ignition system.

How to get rid of unnecessary details

Any 16-valve engine has a plastic protection installed on top. But the protective cover can always be removed by simply pulling the part up. By the way, the rubber supports on the covers of motors 21126 and 21127 will be the same (see figure).

Cover and 4 supports, motor 21126 Cover and the same supports, motor 21127

It is recommended to unscrew the filler plug, but you can leave it in place. The lid must be pulled up, snapping off the supports one by one.

Practicing on motor 21127 Four supports snapped off

Everything looks more complicated than it actually turns out to be. Try it!

Actions before replacement

First of all, we recommend disconnecting the negative terminal of the battery. To do this you need a key “10”. Then disconnect the ignition coil connectors. The appearance of one connector is shown below.

By pressing the latch, the connector is pulled up

Next, taking a TORX E-8 wrench, unscrew the screw securing the coil.

Need a TORX spanner

The coil itself can be pulled out by holding it by the connector body.

The connector will not break, try it

Finally, the engine is ready to replace the spark plugs. This process is discussed further.

Do not allow dust to get into the spark plug well! If necessary, you can use a can of compressed air.

We change the spark plugs ourselves

Let's say all the wells were open, and now you can see the contacts of the spark plugs.

Only one well is open here

Taking a high 16 socket wrench, dismantle each spark plug. It is better to use a special tool - that is, a “spark wrench”.

All spark plugs should come out easily

Installation is carried out in the reverse order, but the following requirements are observed:

1. First, taking the spark plug body with your hands, screw it in without using a key;
2. The key must be rotated with a force of 25–30 N*m. Do not exceed these numbers!

It is usually recommended to change spark plugs “one at a time”. This advice will be useful for beginners.

If there is oil inside the wells, you need to “get it wet”. The oil itself will not cause harm, but sand and dust will get into the cylinders with it.

Replacing spark plugs - Lada Kalina Blog

Since my Kalina’s mileage has long exceeded 30,000 km, I decided to replace the factory spark plugs with new ones, although, to be honest, the factory ones still felt fine. In cold weather it started up to -20 the first time, and if the thermometer dropped even lower, then the second time. At idle, of course, the tachometer needle floated a little, but it was barely noticeable to the eye. In short, we could still drive, but since it is written in the Murzilka - change it after 30,000 km, then we will follow its instructions and recommendations.

It didn’t take long to choose a company, since most car owners speak quite well about NGK spark plugs, and the main thing here is not to run into a fake. If you have a 16-valve Lada Kalina, then you need to take NGK No. 11, and if you have a regular 8-valve engine, then No. 13. I’ll describe the whole procedure a little, maybe this information will be useful for girls or beginners.

The procedure for replacing spark plugs on a Lada Kalina:

Before this procedure, it is advisable to wipe everything well and clean it from possible oil stains or dust so that no debris gets inside the cylinder. Now we need either a spark plug wrench or a 21mm long socket.

We remove the wires one by one, you will have to make a little effort, since they fit quite tightly.

Personally, my electrode condition was normal, there were no deposits, oil film or soot on them, the only thing was that there was a reddish coating. And this is also not very good and indicates that the fuel with which I fueled my Kalina contained iron-containing additives, the so-called ferrocenes. This can lead to misfire, loss of power and increased fuel consumption.

When we screw in new spark plugs, it is best to first tighten them by hand, and only then use a wrench.

Advice for beginners: it is better to change them one by one: that is, first unscrew the old one and immediately install a new one, and so on for each cylinder.

Although, it is quite difficult to mix up the wires! But I remember an incident with my father’s VAZ 2112 16-valve, when we put the wires on incorrectly and started the car - it worked like a tractor, all the cylinders were out of tune. After you have installed a new spark plug, put on the wire and carry out exactly the same operation with the remaining cylinders!

That's all! Tighten it better so that no air is allowed to pass through, otherwise over time the spark plug may tear out along with the thread, then you will have to spend another certain amount of money on repairs, but do you need it? At the end of my topic, I would like to arrange a short survey about who uses which companies, besides NGK, and what are their impressions? Let's discuss in the comments below!

ladakalinablog.ru

Selection of components

Symptoms of incorrectly selected spark plugs:

1. the engine does not work stably, troits or stalls;
2. it is difficult to start a cold and hot engine;
3. Misfire occurs, which causes the “Check Engine” warning light to light up on the instrument panel;
4. loss of power;
5. fuel consumption increases.

From the factory, “AU17DVRM” spark plugs will be installed on any VAZ 16-valve engine. They are produced in Saratov under license from BOSCH. There are also two complete analogues recommended by VAZ: DR15YC-1 (BRISK), as well as FR7DCU (BOSCH).

Products

In winter, you can switch to a lower heat rating - “AU14DVRM” candles are suitable. All analogues are presented in the table.

The gap between the electrodes should be 1-1.15 mm.

For winter use, you can reduce the gap - let the value be from 1.0 to 1.05 mm. We have already written about this in more detail in the article: “choosing spark plugs for the Lada Granta.”

Catalog part numbers

If any part is lost during installation, it can be found from sellers by number:

• Bolt TORX E-8 – 21120-1005157-00;
• Ignition coil (module) – 21120-3705010-X (instead of X – numbers 11, 12 or 13);
• Rubber support – 21120-1008658-00 or 01.

Coil selection:

• 11 – DYNATEC (high quality and many fakes);
• 12 – SOATE;
• 13 – NPO “Sever”.

We hope no questions arise here.

By the way, all 16-valve Lada Granta engines bend the valves when the timing belt breaks!

If malfunctions in the VAZ-2190 begin to manifest themselves, associated with poor engine starting or unstable operation, then the probable cause of these unpleasant moments may be the fact of wear of the spark plugs. This factor is especially clearly manifested on 8-valve Lada Granta units. To save yourself from the risk of stopping on the road, you need to regularly check the functioning of the ignition system. Many car owners are interested in the question, which spark plugs are better?

➤ Spark plugs for Lada Granta: selection, cleaning, replacement

The vagaries and failures in the Lada Granta engine depend on many reasons. One of them: the work - good or not - of the spark plugs. Therefore, the list of necessary checks should always include monitoring their condition. Faulty Lada Granta spark plugs will inevitably lead to unstable engine operation.

Clean or change

A very important question for Lada Granta owners: how often should the spark plugs be changed? According to the manufacturer's recommendations, this procedure should be done every 30 thousand km. But harsh practice shows that not all spare parts work for the allotted time. Premature replacement of Lada Granta spark plugs may be necessary if the following symptoms occur.

• When starting the engine, the starter spins for a longer time.
• While the engine is warming up or when driving in neutral, the engine makes strange sounds.
• Fuel consumption has increased.
• Engine power has dropped. This point is especially noticeable when trying to drive up a hill.
• When you unscrew the spark plugs, you discover that they are wet from gasoline. After wiping, after several hours of movement, the candles become wet again.

Of course, some of the problems listed can be caused by other engine problems. Therefore, it is necessary to check the spark plugs for functionality - using a tester or at a car service center on a stand.

If you find carbon deposits on these parts, it is not at all necessary that you will need to replace the Lada Granta 16 or 8 valve spark plugs. In many cases, it is enough to clean the existing ones. Especially if the car has not covered very many kilometers since the last replacement. It all depends on the type of soot.

1. Brown, gray-yellow coating with slight wear of the electrodes. Both the spark plug and the motor are in good working order.
2. Black coating of a velvety structure with a touch of soot. Either late ignition or too rich air-fuel mixture. The air filter and DTOZh must be checked.
3. Oily coating. Caused by lubricant entering the combustion chamber. Possible causes include: wear of valve stem seals, piston rings, and valve bushings.
4. Red soot. Appears when there are anti-knock additives in the fuel. Or the exhaust gas neutralizer has failed.
5. White soot. Low quality fuel was used or the ignition timing parameters were set incorrectly.
6. Ash soot. Looks like a light brown crust. The cause of the problem may be the valve stem seals.

In cases 1, 2 and 5, the spark plugs can be cleaned and used further. In 3 and 4, replacement of spark plugs is required. In the latter, it is better to install new candles, but if this is not possible, you can temporarily use the old ones after cleaning.

To restore the functionality of the candles, you need to follow this algorithm.

• Disconnect battery.
• Remove the spark plugs.
• Check the elements for the possibility of further use by analyzing the type of plaque on them.
• Pour cleaning product into the container. You can use a disposable glass.
• Dip candles into the composition and soak them in it for 30 to 40 minutes.
• Rinse the elements under cool running water, and then treat with gasoline.
• Use a brush or brush to remove any remaining dirt and wipe the spark plugs dry.
• Check with a feeler gauge whether the remanufactured spark plug meets the requirements. Lada Granta gaps should be within the limits between 1 and 1.13 mm.
• If necessary, adjust the gap of the Lada Granta spark plugs by bending the side electrode.
• Install the restored candles in their proper place.

When cleaning spark plugs, do not use sandpaper or hard brushes. On modern spark plugs, the electrodes are coated with a special coating. If it is damaged, the spark plug will become inoperative.

Replacement on 8-valve models

Before changing the spark plugs of a Lada Granta of any configuration, you should disconnect the battery, for which the negative terminal is removed from it. Next, we change the spark plugs on the Lada Granta in accordance with the following algorithm.

• We dismantle the tips.
• We clean the dust and dirt around the candles - foreign inclusions should not get into the wells.
• Use a socket or a special 21 key to unscrew the elements.

• We screw new spark plugs into their place. First by hand, then we tighten it with a key.
• We return the tips to their place. If you have forgotten which of them corresponds to which element, check the numbering on the ignition coil.

When replacing spark plugs, do not tighten them too much - you will break the threads in the socket.

Replacement on 16-valve models

If the engine on your Lada Granta is equipped with 16 valves, the process of replacing spark plugs will be somewhat more complicated. After de-energizing, proceed as follows.

• We dismantle the decorative panel.
• Press the latch without excessive zeal.

• We turn off the ignition coils - this modification of the engine has a personal coil for each spark plug. To do this, use an E-6 asterisk to unscrew the bolts and remove the coils.
• Using a 16mm spark plug wrench, unscrew the element to be removed and screw in the new one.

• We put on the coil, tighten it and connect the wire plug.

• All that remains is to put the lid back in place, and you’re done.

Reviews

I prefer to use "Japs". I recently changed it on my Grant after 45 thousand mileage! Their quality is excellent and their service life is impressive (if, of course, you drive carefully and regularly clean and check their condition). Vladimir Ivanovich

I have used Ladas my entire automotive life and installed BRISK spark plugs on them. And it pulls well and is reliable. But, really, you need to check it regularly and change it after about 25,000 miles - then the engine works well and without any whims. Sergey

About aspects of the ignition system

In the engine compartment of the Lada Grant there is a 1.6-liter 4-cylinder engine, the design feature of which is the presence of both an 8-valve cylinder head and its 16-valve version. Depending on the type of valve mechanism used, the power indicator is equal to 82 hp. With. or to 106 “forces” respectively.

The control module is designed to monitor the correct functionality of the ignition circuit. This device receives certain impulses sent by sensors and processes them. The ECU then generates a voltage that is subsequently addressed to the coils.

For different valve mechanisms, the coils have their own design and location configuration. So in 16-valve variations of LADA Granta engines, these components are located in separate wells, the number of which is “4” (according to the number of cylinders).

For 8-valve units, the manufacturer used a single-casing design, which is essentially a step-up transformer. This device is equipped with a single primary winding with a middle location of its output and two secondary ones, whose output contacts are connected to spark plug tips. The ignition circuit of the Lada Granta, which has an 8-valve timing unit, has a so-called “idle” spark method. The essence of the declared technology lies in the synchronous generation of a spark in two cylinders at once. In the first of them (conditionally) it ignites the mixture and is considered “working”, and in the other it “skips in idle mode”.

What is the algorithm in the operation of the ignition unit?

By means of spark plug electrodes, a spark is generated in the combustion chamber, which allows the mixture to ignite. The operation of these components involves harsh conditions involving exposure to very high thermal and electrical loads. The temperature indicator of the spark plug electrodes of working spark plugs can reach 900 degrees. In the Lada Granta ignition system, the spark plug arc discharge, which generates a spark, is characterized by a potential of 30 - 40 kV.

The severity of the operating mode of these elements directly affects the resource. Also very common is the appearance of carbon deposits on electrode surfaces, which is caused by disturbances in the combustion process.

We should not forget an important point related to the detrimental effect of unit overheating on the life of most components of the ignition circuit. It is candles that are subject to increased requirements in terms of ensuring the ability to function under conditions of increased thermal disturbances.

The stability of spark production at the electrodes indicates the normal functioning of both the spark plugs themselves and other components of the ignition unit. To ensure trouble-free operation of system components, the following postulates should be strictly observed:

Grant's trunk

• spark plugs are replaced only with those consumables that are approved by the regulatory requirements of AvtoVAZ;
• exclude violations of the frequency of replacement of components (the duration of operation of one set should not exceed 30 thousand km);
• perform maintenance actions with the required regularity;
• tend to use motor oil and fuel only capable of having high-quality conditions.

Replacement and maintenance points

What are the best spark plugs? The manufacturer strongly recommends installing spark plugs on the VAZ-2190, version 8 valves that meet the standards of the AU17DVRM brand. These products are of domestic origin, or more precisely, they are manufactured at ZAZS Russia OJSC.

Catalog code – “21110-3707010-00”.

If we consider foreign analogues, we should highlight the following:

• "WD7DFC", produced by the German giant "BOSCH";
• “BCPR6” from the “ES-11” series from the Japanese brand “NGK”;
• "DR15YC" from the BRISK corporation (Czech Republic).

Each car owner decides for himself which spark plugs are best.

The entire set (4 pcs.) should be replaced. When choosing the parts you are looking for, pay attention to their technical characteristics. The following set of parameters will be relevant for a candle:

• diameter of the threaded section;
• its length;
• heat number.

The purchased spark plugs must fully comply with the needs of the LADA Granta engine in terms of the indicated characteristics.

Spark plugs for Priora, Kalina and Grant - which ones to buy?

The line of cars from VAZ - Priora, Kalina and Granta are similar in many ways. Each of these cars has different modifications with different engines. But, in fact, the main difference in the engines of these models is only in the number of valves.

Spark plugs for Priora, Kalina and Grant differ only depending on whether an 8- or 16-valve engine is installed, regardless of the generation or year of manufacture of the car. Original spare parts for all three models are supplied by the Russian company ZAZS OJSC.

According to the rating of spark plugs for Lada Priora on PartReview dated 05/05/20, owners prefer Bosch products. Manufacturers Denso, BRISK and Finwhale also stand out.

Spark plugs for Kalina, Priora and Grant - which ones to choose?

Lada Kalina (1st and 2nd generations), Granta and Priora were equipped with both 8 and 16 valve engines. And although they differed for each car, they were still structurally very similar. Therefore, the same spark plugs were installed on all three cars; the differences are only in the article numbers. Spark plugs, as mentioned above, differ on all cars only depending on the number of valves in the engine.

If we talk about the rating of spark plugs for VAZ (Lada) Kalina on PartReview dated 05/05/20, owners prefer BRISK products. Manufacturers Denso, EZ and Bosch also stand out.

In the original, all three cars are equipped with ordinary nickel spark plugs, with one ground electrode. The main differences between the spark plug for 8- and 16-valve engines are the size of the key for screwing it in.

More details about sizes and original articles in the table below.

Article Number of engine valves Thread / thread length, mm Key size Gap, mm Heat rating * Material of the central electrode

*According to Champion nomenclature (Russian standard)

Despite the fact that each car has a different article number of original spark plugs, they are interchangeable. Original spark plugs can be found on sale directly from the manufacturer “ZAZS”. For 8-valve engines they have article number A17DVRM, and for 16-valve engines - AU17DVRM.

The most well-known replacement models from other manufacturers are presented below.

ManufacturerArticlePrice, rub (per 1 piece)

As surveys on some popular automobile communities on the RuNet show, the most popular brands among owners of VAZs of the tenth family are NGK and Denso. In addition to ordinary nickel spark plugs, owners of the cars described in the article often resort to installing more advanced iridium spark plugs. Their service life is consistently three times longer than usual, or even more. In addition, they also slightly improve the responsiveness of the engine. The most popular spark plugs for these cars are from Denso. For 16th grade. this is IK20 at a price of 520 rubles/piece, and for 8 cells. — IW20, price — 590 rub./piece.

According to the rating of spark plugs for VAZ (Lada) Granta on PartReview dated 05/05/20, owners prefer Bosch products. Manufacturers Denso, Finwhale and BRISK also stand out.

How to adjust the gap?

Performing maintenance involves cleaning the electrodes from accumulated carbon deposits and adjusting the gap. This parameter should not be allowed to exceed the manufacturer’s permissible requirements. The process of the spark plug involves reducing the height of the central electrode with the simultaneous formation of a rounded depression on the inner sphere. This implies an increase in the gap, the value of which is subject to adjustment. It is set using probes and corresponds to the limits of 1.0 - 1.5 mm. If the gap is set correctly, the probe will penetrate between the electrodes with a noticeable tension.

Clearing away cinder deposits

You should resort to this procedure if the need arises and cinder deposits have accumulated on the electrodes. Here we do not recommend using pointed objects made of hard steel. Use a wire brush with soft bristles or sandpaper. Alternatively, you can resort to cleaning using a chemical or thermal method.

Inspect the condition of the electrodes after 10 thousand km or earlier, if the engine prompted this by its capricious operation. If the intensity of use of a LADA Granta car is low, then inspect the spark plugs once a season (twice a year).

Replacing spark plugs is very common, and the owner of a Lada Granta is not provided with a full guarantee of the high-quality functioning of the system and, accordingly, the engine. Also, no one will undertake to claim that the new spark plug will withstand the regulatory service life of 30 thousand km.

We change spark plugs if the following circumstances occur:

• there were signs of a poor (not the first time) engine starting;
• the unit is troit;
• traction performance has deteriorated significantly;
• mileage exceeded its regulatory limit of 30 thousand.

Be aware of the risk of injury from high voltage traveling through the wires leading from the coil to the spark plug tips. An important element of the spark plug is replacing them, so it must be done carefully.

Comparison of A17DVRM analogues produced under different brands

One of the online publications conducted a comparative test of spark plugs intended for the VAZ-21116 engine. We tested analogues of the A17DVRM spark plug, supplied by the following companies:

• APS, Bosch, Brisk – Russian production;
• Bosch Platinum, Beru, Finwhale – Germany;
• NGK, Denso – Japan;
• Eyquem - France;
• Champion – “made in the European Union”.

Note that testing was carried out on an 8-valve VAZ-2111 engine (injectors, lambda probe, without catalyst, “January-5.1”). All measurements were carried out on a bench. Selection of spark plugs for 8-valve engine 21116

The results of the tests performed are presented in the photo in the form of graphs. As you can see, it still makes sense to buy imports: using spark plugs from Bosch, as well as products from the Finwhale, Brisk and Champion brands will provide a noticeable increase in power. If you want to save on fuel, then ask for NGK products in stores. Additional comments are unnecessary here.

Forced engines are characterized by an increased compression value, and VAZ engines. By installing Brisk spark plugs, you don't have to worry about sparking at high pressure. But note that NGK candles have similar characteristics. It turns out that NGK products should be considered the optimal choice, however, recently counterfeits of this brand have appeared. And the “remake”, it seems, is now coming from France, as described in the film.

Let's sum it up

Timely routine maintenance of the Lada Granta ignition system is the main guarantee of uninterrupted engine functionality. As you can see, replacing spark plugs is not that difficult. This measure will also reduce fuel costs.
