spark plug

The spark plug is a key component in a gasoline engine’s ignition system. Its primary function is to convert the high-voltage electrical energy generated by the ignition coil into an electric spark, igniting the air-fuel mixture in the combustion chamber and thus driving the engine to completion. The spark plug is the “starting point” of engine ignition, directly impacting the engine’s starting performance, combustion efficiency, power output, and emissions.

Features：
Heat & pressure resistant: Built to withstand extreme conditions in the combustion chamber.
Stable ignition: Ensures reliable performance under various speeds and loads.
Service life: Regular plugs last ~20–30k km;
