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.

The 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/piece. And for a car with a 16-valve engine - IK20 with a price of 520 rubles/piece.
