Which spark plugs are better for VAZ-2112 injector 16 valves

What to choose?

For the VAZ-2112 there are many different brands of spark plugs, which differ in type, composition and appearance. Therefore, what exactly to choose is up to you, and below we will tell you about each of those that are most often chosen by the owners of “two-wheelers.”

• JSC ZAZS, Russia AU17DVRM
• BERU, Germany 14FR-7DU
• CHAMPION, England RC9YC
• NGK, Japan BCPR6ES-11
• DENSO, Japan Q20TT
• BRISK, Czech Republic DR15YC
• BOSCH, Germany FR7DCU
• FINWHALE, Germany F516

ZAZS

Standard spark plugs that are supplied with all VAZ cars from the factory. Despite the fact that the manufacturer recommends replacing only this model of spark plugs, many car enthusiasts do not share this opinion and use other brands.

Beru

BERU 14FR-7DU spark plugs have a special modification in the form of a copper central electrode with a nickel shell. This design increases resistance to wear and corrosion. The conical shape of the skirt allows you to very quickly switch to self-cleaning mode, which has a beneficial effect when traveling short distances in the city. Thanks to the increased spark power, the fuel burns most efficiently to the maximum - and this is already tuning the ignition system and engine.

Champion

Spark plugs from Champion. Made in the EU, Champion RC9YC spark plugs offer low fuel consumption, high stability and increased power at high engine speeds.

NGK

Japanese candles NGK BCPR6ES-11 are among the most affordable on the market in the price category.

An engine with such spark plugs runs very stable, and with the throttle valve open to full, it can develop 4.5% more power than with standard spark plugs. When tested on a stand, it shows a result in fuel consumption that is 3.9% less than the “stock” figure.

Denso

Spark plugs from Denso.

DENSO Q20TT has a thin electrode made not from precious metals, which primarily has a beneficial effect on its cost. Thanks to this spark plug shape, the engine experiences a steady increase in power, acceleration and dynamics come to life, as well as a reduction in fuel consumption.

Many owners of the VAZ-2112 note the smoothest and most stable operation of the engine at idle speed.

Brisk

Brisk DR15YC made in the Czech Republic, has a copper core and an extended central electrode insulator. The latter allows it to quickly switch to self-cleaning mode, so this spark plug is well suited for cars operated in urban environments. The interval for replacing spark plugs directly depends on the type and quality of fuel used.

Bosch

Spark plug from Bosch.

Bosch FR7DCU have a copper core in their design, placed in a chromium-nickel shell, which increases the electrode's resistance to corrosion and erosion. Nickel coating prevents sticking of threads and protects the spark plug body from the harmful effects of aggressive environments. The spark plug from this company showed stable, average results in terms of fuel consumption and acceleration dynamics.

Finwhale

Spark plug from FINWHALE.

The body of the Finwhale F516 spark plug is galvanized and made of highly ductile steel, equipped with high electrical insulation, due to which heat, conductivity and mechanical strength are increased due to the high content of aluminum oxide on the insulator. To ensure that the electrodes burn out less, they are made of a nickel alloy.

After carefully reading this article, you can easily choose the candles that are right for you, based on your needs, capabilities and purpose.

User survey

VAZ 2110/2111/2112 cars are the tenth series of domestic cars produced since 1995. Such cars were produced only with gasoline engines (injector and carburetor). Spark plugs for each car of the tenth family come with different part numbers, but in fact they are very similar in size and parameters. The differences in spark plugs on these three cars are due to different engines, although all of them are developed on the basis of a 1.5-liter 8-valve carburetor engine from a dozen.

The VAZ subsidiary Lada Image supplies original spark plugs to the assembly line. The original spare part is sold in Lada branded packaging. But the manufacturer is the domestic company OJSC ZAZS, Engels.

Spark plugs for VAZ 2110, 2111, 2112 – which ones to put on the injector and carburetor

The spark plugs on the VAZ 2110/2111/2112 have a nickel central electrode, single-pin. For the VAZ 2110 the base engine is an 8-valve carburetor, for the 2111 it is also an 8-valve engine, but with an injector, and for the VAZ 2112 it is a 16-valve, injection engine. But in fact, each car was equipped with all these engines and their modifications. Therefore, spark plugs differ in the context of the 3 main base engines.

On each engine, the spark plugs have different markings, but for an 8-valve engine with an injector and carburetor they are the same and differ only in the size of the gap. Therefore, they can be interchanged by first setting the required gap. For VAZ carburetor engines, it is recommended to set it somewhere within 0.7 mm, but on injectors - 1 mm.

16-valve power units already have spark plugs that are slightly different from the previous ones. Therefore, it is not recommended to install them on 8-valve engines. The dimensions and article numbers of the original candles are presented in the table below.

*according to Champion nomenclature

In fact, under the article numbers 21080-3707010-86 and 21110-3707010-86, which go to 8-valve valves, there is the same model of spark plug, only with a different gap. Directly from the manufacturer, it has the article number A17DVRM, the average price is 140 rubles/piece. And under the article number 2112-3707010-01 (for 16 valves) there is a spark plug AU17DVRM, the average price is 200 rubles/piece.

A17DVRM.

AU17DVRMSThe most commonly used substitutes are listed below. Ten and eleven have the same analogues, only before installation it is recommended to check the gap and, if necessary, set it to the recommended values.

It is worth saying that NGK spark plugs are a favorite among owners of these cars. They have the highest popularity and the most positive reviews.

From the factory, the VAZs in question are equipped with ordinary nickel spark plugs, which do not have the longest service life and have a low ignition rate of the fuel-air mixture. Therefore, drivers often resort to installing more expensive spark plugs with iridium thin electrodes. The cars in question are most often equipped with such spare parts from Denso.

For VAZs with 8-valve engines, this is the IW20 model at a price of 590 rubles. /PC. And for a car with a 16-valve engine - IK20 with a price of 520 rubles.

Studies show that such candles have a “hotter” white spark. And due to the fact that the iridium electrode is several times thinner, the spark does not dissipate. In practice, there is a slight improvement in the dynamic characteristics of the motor, as well as a 3-4 times increased service life.

The ignition system is one of the main control systems of the vehicle's power unit. It is designed for timely ignition of the fuel mixture.

The spark plug is a very important and rather capricious element of an internal combustion engine. The stability and efficiency of the engine depends on the correct choice of spark plug. You can learn about the main characteristics that you should pay attention to when purchasing from the article below.

The spark plug has long been the subject of jokes and has been played up many times in driver folklore, and this is not surprising - spark plugs play an important role in a car and sometimes cause a lot of problems for drivers. Read about what spark plugs are, what they are, how they are characterized, and how often they need to be replaced.

When to change spark plugs on a VAZ 2110/2111/2112?

According to the maintenance regulations for VAZ 2110, 2111 and 2112, spark plugs must be changed every 30 thousand km. According to the experience of the owners, their actual service life is slightly lower, and rarely reaches 25 thousand km. This is especially true if the car is operated in difficult conditions, or in severe frosts, since when starting a very cool engine, they can be filled with gasoline.

Which spark plugs are best for VAZ

If you take a car of the 10th family or Priora, then you need recommended spark plugs for 16-valve engines, which have several differences from classic spark plugs for 8-valve engines. Candle manufacturers On the domestic market you can find many candles from different manufacturers. The highest quality candles are produced under the following brands:

• Valeo;
• Bosch;
• Brisk;
• NGK.

The listed manufacturers are taking various approaches to improving the quality of engine operation. An important role is played not only by the material of the electrodes of the spark plugs, but also by the manufacturing accuracy, especially the size of the spark gap.

Non-traditional schemes

Some of the design solutions in spark plugs of an unconventional design can be called conditionally working - by improving one thing, they worsen another. The simplest example is the NGK V-Line series of spark plugs: their central electrode has a groove, so the spark always jumps between the edge of the electrode and the side one. In theory, this improves ignition of the mixture by moving the spark into a better ventilated space and stabilizing the spark point, but the erosion of such a central electrode is accelerated.

Some of the candles on the market cannot be classified as anything other than “Herbalife” from the car market: all sorts of “pre-chamber”, “torch” and so on candles, at best, work no better than standard ones, at worst, they quickly deteriorate. For example, in the notorious “Bugaets” candles, the soldered skirt not only worsened the ventilation of the spark gap, but also burned out, and sometimes went into “free flight” into the combustion chamber. Of the designs that are workable, but useless in the practice of an ordinary motorist, we note only spark plugs that do not have a side electrode at all - they were originally created to work in ultra-high boost engines in order to avoid overheating of the protruding side electrodes; in a normal city cycle on a “civilian” boost level motor, they They clean themselves disgustingly and guarantee rough idling even on ideal quality gasoline.
