NGK is one of the world's leading manufacturers of spark plugs. As an original equipment manufacturer for renowned vehicle manufacturers, NGK is there from the very beginning when the spark ignites.
An NGK spark plug is supplied as it is fitted in the vehicle ex works. The heat value and spark plug design correspond to the original.
The service life of a spark plug is determined by the fuel type, engine condition, operating times and engine temperature. For 4-stroke engines from 250cc, the plugs should be cleaned or replaced after 6000km. For smaller displacements, especially 2-stroke engines, approx. every 2500 km. Even after this mileage, oil carbon deposits lead to starting difficulties and loss of power caused by the spark plug. Increased short-distance operation and poor engine oil quality can shorten the intervals.
