Best Traditional Design Spark Plugs

Hidden under this inconspicuous marking are the original Renault spark plugs created for this engine. Thus, their characteristics are most suitable for operating conditions with the K7M engine, and strict control by the plant guarantees consistent quality.

The manufacturer of the original spark plugs is Eyqiem, a French company that is the main supplier of spark plugs to the assembly lines of many European factories. The design of these spark plugs takes into account a number of points specific to an eight-valve engine:

The relatively large extension of the central electrode into the combustion chamber allows for stable ignition of the mixture under conditions of its uneven distribution throughout the cylinder (the spark plug is shifted to the edge of the combustion chamber; in a number of modes, the actual composition of the mixture at the walls of the combustion chamber and in its volume differs). Also, moving the spark gap deeper into the combustion chamber improves its ventilation, ensuring ignition stability.
Two side electrodes increase the resource - the spark, contrary to popular belief, does not jump between all electrodes at the same time, but between the pair where the conditions for this are easier (shorter distance, thinner deposits, and so on). Schematically, the operation of multi-electrode spark plugs can be described as follows: as the “working” pair of electrodes inevitably wears out due to spark erosion, sparking moves to the second pair, although in reality, with precisely maintained gaps, it usually alternates between different pairs.

Rating of spark plugs among cars

Car owners, of course, are more interested in looking at the rating of spark plugs for their car. These ratings do not take into account the PR Score and are based only on reviews of the vehicle listed. Details in the help.

PartReview can offer auto ratings for such popular models as: VAZ (Lada) Vesta, VAZ (Lada) 2107, VAZ (Lada) 2113/2114/2115, VAZ (Lada) Granta, VAZ (Lada) 2110/2111/2112, VAZ ( Lada) 2101/2103/2106, VAZ (Lada) 2108/2109, VAZ (Lada) Kalina, VAZ (Lada) Largus, VAZ (Lada) Priora.

Spark plugs for VAZ (Lada) Priora

for repair of VAZ (Lada) Priora

Finwhale FS-32/516X 3-pin spark plugs, lasted 13,000 km, would have worked further, but with a mileage of more than 11,000 km, the engine began to start poorly when cold, I had to turn the starter longer. I liked Finwhale more than NGK, which cost 30% more. Another reason to stay with the Finwhale is fuel consumption. When I drove an NGK in winter, the BC showed an average consumption of 10.4 l/100 km; after installing Finwhale, the consumption dropped to 9.5 liters.

The time has come for the next maintenance, I always buy consumables from the official distributor. Last year I tested Finwhale spark plugs and found no problems. In winter it started the first time.

This week I decided to change the spark plugs; the old spark plugs were Finwhale FS-30 with three side electrodes. We drove them for about 45,000 thousand km, and they continued to work, but we still wanted new ones. In the store I saw them again, without hesitation I decided that I needed to take them, especially since the price for them had not even changed - 420 rubles. After replacing the spark plugs, I didn’t even take the car for a drive, but my father drove it and says it started pulling better) And it starts easier and faster, well, whatever you say, it’s a new part)

I recently bought Finwhale f510, one of the spark plugs almost immediately turned out to be broken.

For the last three days, traction began to disappear when changing gears from 2-3 and 3-4. I didn’t do diagnostics, I decided to deal with the problem myself, I bought spark plugs for 350 rubles. and a 1250 coil. When removing the coils, I discovered that on cylinder 1 the coil was different from the other three and looked more alive, the springs in the other three were somehow oxidized, then on cylinder 4 I didn’t like the spark plug; there was a layer of scale on it. There were 2 NLC spark plugs and 2 mass flow sensors.

I installed Bosch Itrium spark plugs (Russia) 3000 km ago. I decided to take them off and have a look, because... sometimes the car didn’t start the first time, I took them off and what I saw was gases escaping from the connection between the insulator and the metal part of the spark plug. I bought new iridium liquid liquid coolers, installed them, the engine started running smoothly, I’ll see how long they last.

I have long wanted to talk about an excellent way to improve the performance of a car without resorting to changes in design, and at the same time about an excellent way to save money (especially in our conditions of constantly rising prices). This discovery came to me on the advice of a friend who has been using Denso candles for more than 10 years. Well, he recommended them to me. After reading the characteristics, I realized that even if the mileage is about 50 thousand km, the benefits will already be obvious, but on my Priora I have already run more than 80 thousand on them and have not noticed any negative changes. The car starts more confidently in cold weather, there are no misfires at high speeds. I’ll be changing my car soon and I’ll definitely install a Denso right away on the new one.

NGK spark plugs, wires - there were a lot, I liked the Elephant, now Tesla (as it happened). Wires and spark plugs are easy to check - if the car doesn’t start at -15-20, it’s a good idea to change it, usually once every year and a half - replacement (mileage is approximately 20 tkm).

I had a problem: when I pressed the gas pedal sharply, the engine slowed down, when I pressed it smoothly everything was fine. I installed DENSO, which later cured my illness. All I can say is that the candles are great! I recommend it to everyone!

They cost finwhale and no tripping, but the NGK coils were changed every six months. Finvale candles have a large resource. I myself have driven 15 thousand so far, and some have driven 50 thousand on them.

Rating of the best candles for 2017/2018

Spark plugs are a device for igniting the fuel-air mixture in heat engines. At the time of purchase, you need to pay attention to such parameters as: geometric dimensions (it is very important to choose the necessary dimensions specifically for your car, since if you do not follow these tips, serious damage may occur), heat rating, brand and price.

Therefore, to help you choose the best spark plugs, we analyzed about a dozen different TOPs, selections, including reviews from PartReview, and compiled our own rating of the best spark plugs for 2017/2018.

Spark plug test while driving 2021

I bought NGK BKR6E-11, it seems like they are for 1.6 16V, but according to the catalog they are for a foreign-made engine, before installation I made marks on the nut opposite the side electrode, I decided to see how the spark plugs would fit in relation to the intake valves, how very surprised I was when I saw the marks - all the spark plugs fit completely differently (although the tightening torque seems to be the same), only one spark plug stood perfectly facing the intake valves, and one, on the contrary, stood exactly with its “back” when the side electrode blocks the spark from the intake valves.
I think it’s the spark plugs that are crooked or the threads in the block are crooked. Now I’m seriously thinking about multi-electrode spark plugs, where at least the spark runs around in a circle depending on the resistance of the spark plug. from NGK which multi-electrodes are suitable for our motor? install Bosch five electrodes, it will be better

install Bosch five electrodes, it will be better

yes one central and four in a circle

Actually, these are four-electrode spark plugs, read https://www.bmwgtn.ru/carsystem/svechi1.php

I’m sorry, of course - but you don’t understand this topic at all, at least read the auto review test in my message numbered #100, below is the article “Orienteering”, I still somehow trust the opinion of the experts of ZR and the auto review more than statements like this you. you can google spark plug tests yourself in Behind the Wheel. So it says that the spread of parameters is within the measurement error: rtfm:, in other words, centrumnsk is absolutely right.

PS Try to explain the physical basis for improving engine performance with other spark plugs

but you don’t understand this topic at all. This is correctly noted.

I’m not going to dispute your opinion, and these paid tests are of no use to me, life experience shows otherwise, believe me, over 25 years of driving experience, I’ve tried and experienced a lot of things, starting with the military Urals and ending with Lexus and Priora, and also at your age I tried to make a racing car out of six:shok: but alas

but you don’t understand this topic at all. This is correctly noted.

let it be so: unsure. The money is yours, and I don’t care what you buy and install on your car. I didn’t write advice on candles, but simply expressed my observations and life experience, and what you do is up to you

Sector, I didn’t find these lines there, can you quote them? [email protected] Yes, about 8 valves, but do you know the difference from 16V? Have you really read about physical processes, or rather their difference in 16 and 8 V? OLEG 742, usually when there is an advertisement, it’s written in small print at the bottom as an advertisement, especially since in that article about the location they didn’t say which brands of candles stand up better, and where is the advertising? + I don’t know how to autoreview, but the publication is too rich to be sold on some tests of candles, and tests in general, if they were caught doing this, please send a link to the studio. I will be interested in reading the facts. The magazine is too old and popular, many people want such fame and so they throw mud at them.

so, as I understand, not everyone knows how to read articles from external links, I will duplicate the text and highlight the main points: All three sets passed bench tests in the VAZ-2111 engine. And it turned out that the orientation of the side electrode seriously affects the combustion process! When the electrode “screens” the spark gap, shielding the spark from the flow of the air-fuel mixture from the intake valve, at idle and low loads this causes a sharp increase in specific fuel consumption, and the content of unburned hydrocarbons (CH) in the exhaust gases increases. Moreover, when all four spark plugs are in the “closed” position, the engine generally refuses to idle at speeds less than 1200 rpm! At low loads, the difference in specific fuel consumption was 15%, and in CH emissions - even up to 80%.

centrumnsk would like to apologize to you, I didn’t immediately see your age, again your words are just the words of a driver with 25 years of experience, technology does not stand still in the auto industry, as well as in the digital/computer industry, in the modern world you need to remember old experience but always take into account modern technologies. Otherwise, you can remain in the past. and unfortunately, I myself had to deal with diagnosticians at stations with a lot of experience, when everyone unanimously said that everything was fine with my engine according to all the sensor readings and graphs in the diagnostic programs, but I felt that something was wrong , and in the end it turned out that the belt jumped or was installed incorrectly by only 1 tooth. Then the loss of power was very noticeable for me, and no one but me saw it. and I immediately pointed out to them that the air consumption had changed (it was 8-9 kg, now 6-7), the instantaneous fuel consumption had changed (it was 0.8 l/hour, now 0.7) (all at warm idle) everyone said that this was within the normal range.

and I do not undertake in any way to convince you all, I just laid out my observations on the curvature of the thread of the block and candles. and let everyone draw their own conclusions about the influence.

It is truth too. Almost all companies producing candles try to produce candles with a thin central electrode. If there was no effect from the thin electrode, then they would not have been released. Firms don't throw money around in vain.

NGK

Country of origin: Japan. Spark plugs from ]NGK[/anchor] have stable spark generation and are also resistant to the appearance of chemical deposits. The model range is represented by the following lines: NGK LPG LaserLine (for gas engines), NGK IRIDIUM, NGK Laser Platinum, NGK Racing Competition. The brand is often compared to Champion.

What they praise for : High-quality work at high voltage, durability, iridium coating. Why they criticize : The side electrodes have rough stamping, price.

Parameters and characteristics of spark plugs

The main parameters of the characteristics of candles are the size and heat rating, in addition to the fact that they also differ in the number of electrodes and in the material of manufacture. Let’s look at all these points and how they affect performance in order.

One of the most important thermal characteristics of spark plugs is the so-called heat number . This is a parameter indicating the pressure at which glow ignition occurs. Usually, the vehicle documentation indicates the brand of spark plugs and the heat rating that should be used in it. Try to follow these recommendations.

The heat rating is divided into three ranges:

cold candles (calc. from 20 and above);
hot (11 - 14);
average (count from 17 to 19).

This parameter indicates the thermal operating conditions of the candle ; the higher it is, the higher temperatures it can work with.

In addition to the heat rating and geometric dimensions, there is another quite important parameter when choosing candles - their design.

Specifications

General information about spark plugs

The technical characteristics of the spark plug include:

thread diameter;
key head size;
thread length;
gap between electrodes.

The diameter of automotive spark plugs is usually 14 mm. Based on thread length, candles are divided into three groups:

1) short – 12 mm;

2) medium – 19-20 mm;

3) long – 25 mm or more.

The length of the threaded part of the spark plug will depend on the engine power - the more powerful, the longer the spark plug . This design is due to the fact that the temperature is distributed faster and more evenly throughout the long body. The most common size tool for screwing in spark plugs is a 16 mm socket, less commonly – 14 and 18 mm. The gap size between the central and side electrodes for all spark plugs is within the range of 0.5 mm - 2.0 mm, but the most common is 0.8 or 1.1 mm.

The characteristics of a spark plug are marked with a standard designation - an alphanumeric code, which is applied to the spark plug and to the packaging. Typical designations for candles vary depending on the manufacturer; there are no standardized designations.

Best Multi-Electrode Spark Plugs

Denso K20TXR

These candles are a prime example of how to save money without overpaying for the automaker's logo. In terms of characteristics, design, and appearance, they are no different from models produced to order from automakers. You can safely buy instead of the original - other than saving money, there is no difference.

The model belongs to the budget class - nickel coating. However, several side electrodes provide stable sparking.

Advantages:

Highest quality workmanship, no manufacturing defects.
Reasonable price, below platinum. However, there are no differences in quality.
Good protection against spark erosion.
High corrosion resistance, after all, nickel coating.
Wide slots on the nut.
As for candles without the use of noble metals - a high resource.

Flaws:

It is inconvenient to adjust the gap - the side electrodes are too strong.
On liquefied gas the results are mediocre.

Bosch FR7LDC+

Economy class in the line of multi-electrode spark plugs. The cost is significantly lower than the original ones, while the characteristics are practically the same. Yttrium coating. Not platinum, of course, but it increases the resource.

When low-quality fuel gets into the cylinders, the performance deteriorates, causing economy class costs.

Advantages:

Excellent price, while the resource is not much less than the original.
When working with high-quality fuel, good efficiency indicators.
The yttrium coating guarantees high resistance to spark erosion.

Flaws:

The characteristics strongly depend on the quality of the fuel. Not suitable for use away from approved network gas stations.
Due to the high popularity of the model, there are a lot of counterfeits on the market. It is quite difficult to distinguish from the real one.

NGK BUR6ET

The candle is not cheap, but the difference in cost with the original is compensated by its outstanding properties. The electrodes are coated with nickel, which guarantees corrosion resistance. Most consumers note stable operation in any speed range. This is also confirmed by professional tests. Candles of this model are always in the top three.

Advantages:

Three side electrodes guarantee sparking under all conditions.
They tolerate low quality fuel quite well.
Good economy, especially under load.
The increase in power compared to standard spark plugs is more than 4%.
The resource exceeds the replacement service intervals by a factor of two.

Flaws:

High price. That's a lot for nickel plating.
Exhaust toxicity is not the most outstanding.

Brisk Premium LOR15LGS

Original design of the electrode module. Four side electrodes are located below the cut of the central rod. As a result, sparks entangle the central electrode in a web from the insulator to the cut. Ignition reliability increases, spark density is 360⁰.

This is a patented system, there are practically no analogues. Thanks to the dense spark, ignition occurs at the very initial phase of fuel supply. Cost-effectiveness at a high level. Unfortunately, high technology costs a lot of money - this is one of the most expensive candles on the market.

Advantages:

Complete combustion of the fuel ensures outstanding efficiency.
Performance does not depend on the quality of the fuel.
Ecology is at a high level, one of the best indicators.
The increase in power at high speeds is more than 5%.
Resource more than 50,000 km.

Flaws:

The highest cost is for regular candles.
Low spark stability at low voltage.

Beru Ultra-X 79

The economical price is combined with excellent consumer properties. This candle has contradictory indicators: the manufacturer in its technical specifications indicates incompatibility with LPG, while users, on the contrary, note the high quality of operation on natural gas.

The spark plug has four electrodes, located at different distances from the core. Two electrodes have a gap of 0.8 mm, the rest - 1.2 mm. As a result, an equally stable spark is formed under different operating conditions, even with a heavily smoked insulator. The result is an imitation of a surface discharge in a traditional design.

Advantages:

The highest efficiency among multi-electrode designs.
Low exhaust toxicity levels.
Reliable spark even when the electrodes are heavily soiled.
Users note a decrease in operating engine noise.
Stable operation on liquefied gas.

Flaws:

Low power gain with the throttle valve open – no more than 3.5%.
It is not possible to set the required clearance to vehicle specifications.

Hella

Country of origin: Germany. The company uses high-tech materials in the manufacture of candles that are resistant to corrosion and spark erosion. The model range is represented by the following lines: Hella Energy, Hella Energy Pro Spark Plug, Hella Platinum Spark Plug, Hella Iridium Pro Spark Plug.

What they praise for : Stable operation, long service life. What they criticize for : Price.

Spark plugs for Priora: choices

The manufacturer of Priora recommends installing domestically produced spark plugs, but they can easily be replaced with foreign analogues. Let's consider the classification:

All spark plugs are divided into two-electrode and multi-electrode. Two-electrode ones have a side and a central electrode, while multi-electrode ones have one central and several side electrodes, respectively (usually 3). It is believed that multi-electrode ones have a greater lifespan and durability.

Spark plug

Spark plugs differ in Priora and by type of material. So, the standard, classic option is copper electrodes. There are also rarer materials: iridium, platinum. Thus, iridium spark plugs on Priora are characterized by a smaller diameter of the central electrode, which ranges from 0.7 to 0.4 mm, while in standard nickel spark plugs this parameter is 2.5 mm. And a completely new product is pre-chamber spark plugs, in which the body itself is given the role of electrodes.
Also, spark plugs are divided by thread diameter and size for the wrench head. Thus, spark plugs for a 16-valve Priora have a smaller thread diameter and wrench head size than spark plugs for a Priora 8-valve model.
There are also four types according to such a parameter as heat value. The heat number is the average pressure at which it is easier to heat candles during testing. So, they are distinguished by types: cold type (heat number above 20), medium type (17-20), universal type (11-20), hot (11-14).

It is not always easy to figure out such complex technical parameters on your own, because a beginner does not understand many things, for example, what is the spark plug gap on a Priora. Therefore, when deciding which spark plugs to install on a 16-valve or 8-valve Priora, it is best to turn to specialists or follow the recommendations of the car manufacturer.
