Pack of 10 Naraku spark plugs 10-R8-L: 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 and long-life repair.

The service life of a spark plug depends on the fuel type, engine condition, operating hours and engine temperature. For 4-stroke engines with 250cc or more, the spark plug should be cleaned or changed after 6000km. With smaller capacity, especially 2-stroke, approx. every 2500km. 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.
