spark plug NARAKU 14-R8-LS (BR8ES)

Naraku spark plug, as also fitted in the vehicle from the factory. The heat value and plug design correspond to the original.
Produced according to OEM guidelines of Japanese vehicle manufacturers for a perfect and long-lasting 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 engines, approximately every 2500km. After this mileage, oil carbon deposits on the spark plug lead to starting difficulties and loss of power. Increased short-distance operation and poor engine oil quality can shorten the intervals.
