How to choose spark plugs for VAZ

Sometimes motorists do not attach special attention when choosing spark plugs, and in vain. After all, they are the most important components of the entire ignition system, and the engineering of the engine depends on the quality of timely sparking. The main characteristics for which you need to pay attention to the purchase of candles is a calil number, the size of the spark gap, the ability to self-cleaning, service life, thermal characteristics, the number of lateral electrodes and operating temperature. Let you not scare a large number of characteristics, with a detailed study of them to choose the spark plugs will not be much difficult.

When choosing a candle, the first thing to pay attention to is a caliper. The parameter is conditional and selected precisely for a particular engine. This number shows the pressure in the cylinder, in which the rolling ignition occurs. The use of candles with a slightly large caliling value is allowed, but it is strictly prohibited to use with a smaller value.

The other conditional characteristic is not a quantitative assessment - the ability to self-cleaning. All manufacturers promise high self-cleaning, but it is possible to check it only in practice. A good candle should not be covered with nagar when warming up to operating temperature.

The clearance on the candlelight or spark gap between the side and central electrodes manufacturer sets a certain type defined for each type. For VAZ, it is suitable with a value of 0.5-0.6 (0.7-0.8) MM firms Bosch, Beru, Champion.

Spark plugs have one side and one central electrode. Recently, manufacturers have begun to produce with 2-4 electrodes. They do not form a few sparks, but only make sparking stable. As a result, more stable engine operation is ensured, the ignition process is improved.

Before buying candles, make a visual inspection. Do not take products with damage, cracks, and before installing again check if the gap is suitable between the electrodes.

Keep in mind, the lifespan of the candles largely depends not only on their design, but also on the operation of the engine, power systems. Modern candles with the right choice, installation and operation should work up to 30 thousand km of mileage.
