DPR9EA base long NGK-9 (average index)

Ideal for the replacement of a worn spark plug or incapable of functioning! Specially designed and developed at NGK to your big displacement motorcycles 4-stroke engines! Here the spark plug NGK DPR9EA-9 very good. Strong and powerful, it will allow better performance of your engine as original. Supplied without olive, this candle has a resistance of 5 kOhm so be careful to use a resistive suppressor 5 kOhm to accompany it. in addition, thanks to its prominent insulator, its electrode is emerged and it will provide better spark.
