Setting of quality spark plugs has a number of advantages. First, there is a significant reduction of load on the engine.

Therefore, this improves his work both when the engine is idling and it is cold. Second, the torque increases throughout the range of revolutions. At the same time flexibility and dynamics of the engine are significantly improved. And the most important fact is that the fuel consumption and the emission of harmful substances into the atmosphere are reduced. The main cause of early failure of the plugs is contamination with products of incomplete combustion or increase of the spark gap because of wear of the electrodes.

In this case, a decisive influence on the performance of the plugs provides technical state of the vehicle engine.
