Pack of 10 Naraku spark plugs 10-R7-LB: Naraku spark plug as it is also mounted in the vehicle from the factory. Heat value and plug design correspond to the original.
Produced according to OEM guidelines of Japanese vehicle manufacturers for a perfect repair and longevity.
The service life of a 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 changed after 6000km. With less displacement, especially 2-stroke, approx. every 2500km. After this mileage, oil carbon deposits lead to starting difficulties and power loss caused by the spark plug. Increased short-distance operation and poor engine oil quality can shorten the intervals.
