What spark plugs does Honda enjoy?
How often do you change the spark plug?
Spark plugs have electrodes, which will wear with the increase of service time. If the spark plug electrodes are seriously worn, the gap between the electrodes will be too large, which will lead to the deterioration of spark plug ignition energy. If the ignition energy becomes weak, it will affect the combustion of the engine. If the internal combustion of the engine is insufficient, the engine power will decrease and the fuel consumption will increase. Therefore, spark plugs are vulnerable parts that need to be replaced regularly.
But the spark plugs of different vehicles are different, and the service life of spark plugs of different engines is also different. Most cars use 40 thousand to 60 thousand kilometers, so there is no need to replace the spark plug. But some cars, especially luxury cars, need to replace the spark plug after using 20 thousand kilometers. Is this because 4s stores deliberately shorten the replacement cycle in order to make more money, or is there something else to hide? I believe that most consumers think that this is because 4s stores deliberately shortened the replacement cycle of spark plugs in order to make money. Actually, it's not like this.
The engines that need to replace spark plugs after 20,000 kilometers are all turbocharged engines. When the turbocharged engine works, the temperature and pressure in the cylinder are relatively high, so the loss rate of spark plug electrode will also accelerate. If the electrode of the spark plug breaks due to high temperature and falls into the combustion chamber, it will directly lead to the scrapping of the engine. Therefore, for safety reasons, some manufacturers suggest that users replace the spark plug every 20,000 kilometers.
