Replacing spark plugs for Lada Vesta. Advice from experts, reviews, service life

Many car enthusiasts underestimate...

...the importance of a car's ignition system.
They systematically violate the terms of technical inspection, and also install spare parts that do not meet the standards. As a result, the engine operates unstably at idle, increased fuel consumption and other problems are noted.

Which candles to choose?

We won’t spend a lot of time choosing, for the reasons given above. This is not as important a factor as the timing belt, ball joint, or wheel bearing. Of course, there is one significant nuance. Depending on which engine is installed - 8 or 16 valves. Our spare part for each of them will be special, not universal.

What kind of spark plugs are installed on Lada Vesta from the factory?

The type of igniters differs in size, depending on the number of valves. In an 8-valve engine the skirt is short, in a 16-valve engine it is long. The standard configuration is from a domestic manufacturer, but nothing prevents the owner from installing imported analogues.

Which spark plugs to choose for Lada Vesta: factory opinion

AvtoVAZ specialists recommend the manufacturer NGK BCPR6ES for both 8-valve and 16-valve engines.

Note to the driver! When replacing spark plugs 16-cl. motor, use a hex wrench set to “14” (it is smaller than for 8-kl).

Standard reel - article number and price

Let's look at the articles, the cost of the IKZ, you can navigate by price. Lately, counterfeit parts have become common. By buying such a fake, you reduce its use by half. In order for the car to work well, the choice of parts should be approached with full responsibility.

• 2112-3705010-12 JSC "SOATE", Stary Oskol - 1165 rubles.
• IKZ – 1000 rub.
• 2112-3705010-11 “ITELMA”, Moscow – 1215 rubles.
• 2112-3705010-13 “NORTH”, Novosibirsk – 1515 rubles.

As you can see, ignition coils are affordable and you can purchase them without significant damage to your wallet. How to distinguish a fake from a factory IKZ:

1. The first distinguishing feature is that the original reel has a body made of plastic, while the fake one is made of metal.
2. The fake part lacks special stamps and a lightning bolt symbol, which indicates high voltage. If you look closely at the contacts of a fake IKZ, you will notice that they are thicker and round. The factory number is marked with an oval on the original part.

Features and purpose of spark plugs

Without the spark produced by the igniter, the engine will not start and the combustible mixture will not ignite.

The average life of an original spark plug is 40,000 km or three years, whichever comes first.

The following models are distinguished: conventional, iridium, one-, two-, three-, four-electrode. Iridium ones are 10–15% more expensive than all other types.

The greater the number of electrodes, the greater the likelihood of rapid combustion of the mixture. For domestic cars this is not so important: one electrode is enough.

How to choose spark plugs for Vesta?

Often, car owners do not pay attention to the choice of igniters. Sometimes, in order to save money, old candles that have been cleaned of carbon are used. However, in a modern engine, high-quality ignition devices play an important role.

There are many models of spark plugs for Vesta on the market: regular and more expensive, high-tech ones (platinum, iridium, multi-electrode). Iridium igniters operate stably over a range of up to 60,000 km. If you compare prices, it becomes clear that one iridium unit costs the same as a set of regular ones. In addition, craftsmen and car enthusiasts note that classic single-electronic devices do an excellent job, provided they are replaced in a timely manner. Therefore there is no point in paying more. The main thing is to choose the right type of device.

Here is a list of qualities that Vesta candles must meet. Uninterrupted operation at voltages up to 40 kV. High thermal conductivity. Resistance to chemical processes and deposits of medium aggressiveness. Ability to insulate at high temperatures (up to 1,000 °C). Resistance to thermal shock.

Vesta cars are factory equipped with Russian spark plugs AU17DVRM or imported DR15YC-1. In the future, for replacement, you can choose other options from the list recommended by the manufacturer.

So, suitable devices are produced by well-known companies: Bosch, Denso, NGK, Champion. Igniters differ by brand and fundamental technological characteristics. They need to be taken into account when preparing tools for replacing spark plugs.

Eight-valve devices can be dismantled with a regular spark plug wrench. If a replacement is made on sixteen-valve valves, then a smaller hexagon is required.

What is the difference between spark plugs for 8- and 16-valve engines?

By and large, there are no differences, except for the size of the key that needs to be used to unscrew the case.

Standard domestic spark plugs are just enough for the intended period, but as noted by car owners, after half the service life, difficulties may arise when starting the engine in cold weather. Spark plugs produced by foreign manufacturers will be a worthy replacement:

Bosch - 0242235913. Price per set is 400 rubles. The cost of one such candle 0241235751 is 120 rubles. You can also find it cheaper, of the same brand, only Russian-made Bosch 0242235666 “Super plus” spark plug. Price – 80 rub./piece.

Yttrium F01H7B0146, a kit from this company will cost 220 rubles.

Spark plugs from more famous manufacturers such as Denso, spark plug “Nickel” Q20PRU11 and spark plug from NGK, product code 2330, will cost 100 rubles per piece. Spark plugs from the expensive price segment such as “Longlife” from VAG (made in Germany) product code 101905601F will cost 350 rubles/piece.

Many motorists advise purchasing spark plugs produced using new technologies. These innovations include iridium spark plugs. On the market they are represented by “Iridium Power” spark plugs from Denso, product code IK20TT, price 560 rub./piece.

But installing such expensive spark plugs on a domestic car is simply unprofitable.

Established rules for replacing spark plugs on a Lada Vesta car

Scheduled replacement of igniters is provided every 40,000 km or every three years, whichever comes first. Mandatory maintenance must be carried out every 15,000 km.

Iridium and platinum igniters need updating every 100,000 km, with maintenance every 50,000 km.

Characteristics of candles

The service life of candles does not particularly depend on the manufacturer, since we are not talking about stuffed technological equipment. In our case, this is a piece of metal of the correct shape with dielectric elements of the body. If the spare part meets certain requirements, then there is no need to fool your head.

• They should not lose their insulating properties at temperatures of a thousand degrees;
• Without interruption, they must provide a stable voltage of 40 kilovolts;
• Resistance to thermal shock;
• The metal must withstand chemical reactions at the installation site;
• The thermal conductivity of electrodes and insulators must comply with the standards.

When replacing, visually compare the old and new spark plugs.

Reviews

Regular or iridium?

AvtoVAZ equips Vesta with Brisk super DR15YC-1 spark plugs. However, there are many offers on the market, and therefore the issue of choice should be looked into separately. And it is the type of product that raises the most questions.

Spark plugs for Lada Vesta can be one of 2 types:

1. Regular;
2. Iridium.

With standard products everything is generally clear. Therefore, the greatest interest concerns iridium ones. Many have heard that they are significantly better, but not everyone is ready to overpay when purchasing - after all, one iridium spark plug costs 2-3 times more than a set of regular 4 units!

In general, as tests show, including those of the authoritative publication Za Rulem, iridium spark plugs for Vesta are much better. They have a noticeably longer service life, which allows them to be replaced 2-3 times less often and save on the work of craftsmen; engine fuel consumption when they wear out increases much more slowly than when using conventional ones. The same applies to toxicity.

If you look at it objectively, it’s worth buying iridium spark plugs for a Lada Vesta if you actively use the car. If this is not the case, then they simply will not pay off, and therefore it is more advisable to get by with simple ones.

It is also worth taking into account the quality of the fuel, because ruining iridium components with “scorched” gasoline is much more offensive than simple ones.
