What are the advantages of changing the spark plug of the car?

1. When the spark plug reaches its normal service life, replacing it is beneficial to the fuel economy (full combustion) of the vehicle.

2. Under the condition of replacing the original spark plug of the same type according to the correct standard parameters, it provides a certain guarantee for the normal work of the engine.

3. Spark plugs are mainly replaced when aging. Of course, there are advantages, and the ignition is more sufficient. Fuel-saving, better emission indicators.

Service life of spark plug

Spark plug failure Under normal circumstances, the service life of spark plug is 15000km, and the service life of long-lasting spark plug is 30000km. With the operation of the engine or the increase of the driving distance of the car.

The discharge voltage required by the spark plug electrode gap is also rising, which will be closer to the voltage limit provided by the ignition coil, so it is more and more difficult to ignite, and finally the fire is cut off.
