Spark plug NGK long thread BP9ES.

As the main source of energy in any petrol engine, a spark plug carries out an essential function: it is responsible for igniting the air-fuel mixture in the combustion chamber of petrol engines.
This combustion process creates energy and allows your vehicle to operate.
To ensure that the combustion process works smoothly, the spark produced by the spark plug must occur just before the piston reaches its highest point and compression is at its maximum, which is why it is important to keep the spark plug in good condition.
