Spark plug motorcycle BP4HS

As the main source of energy in any gasoline engine, an ignition spark plug performs an essential function: it is responsible for igniting the air-fuel mixture in the combustion chamber of gasoline engines. This combustion process creates energy and makes your vehicle run.

To ensure that the combustion process works smoothly, the spark from the spark plug must be produced just before the piston reaches its highest point and compression is at its maximum; that is why it is important to keep the spark plug in good condition.
