NGK Spark Plug BPR6HS

Spark plugs are a vital component of your marine engine ignition system, as they supply the spark that ignites a mixture of air and fuel within the cylinders of your engine, thus creating a combustion that makes your engine operation.

A pure alumina silicate ceramic insulator provides superior strength and heat transfer, whilst a copper core aids heat removal. Corrugated ribs prevent flashover and triple seals prevent leakage.
