Does the spark plug stop working after the replacement period?
The routine maintenance parts on the car have a cycle, the replacement cycle of the spark plug is generally 20,000-100,000 kilometers (different material cycles are different), but it is not said that the official period must not be used, because most products are played in the design life of the surplus, so after the cycle will not cause fatal damage to the engine.
However, after the excessive mileage, the wear of the electrode will accelerate, the electrode gap becomes larger, the ignition instability for the voltage demand is higher, the performance of the light is weak acceleration, ignition fire, oil consumption and other symptoms, serious may also appear electrode fracture damage the engine, so it is recommended that we replace according to the prescribed period, in addition, there will be other parts of the problem.
