Another reason can be mentioned is that the car is using a spark plug with a nickel terminal. Spark plugs made from this material have very poor heat resistance and are easy to melt and wear.
1.5. Spark plugs with large ignition distance
After a long time of use, the ignition process has worn out the center of the spark plug. When the pole is worn, it will cause the ignition gap to increase, reduce the ability of ignition and reduce the power of the car engine. At that time, users need to quickly replace the spark plugs to avoid affecting the car engine.
