NGK spark plugs are designed for a long service life and maximum performance.
Each NGK plug features high alumina ceramics for better heat transfer and electrical insulation. Patented triple gasket sealing process eliminates the possibility of combustion gas leakage. The solid copper core increases heat and spark transfer while the longer insulator nose prevents fouling and misfiring.
- Cold-rolled threads of the NGK Marine Spark Plug helps prevent spark plugs from seizing, even in aluminum heads or salt water conditions
- Double-dipped zinc chromate coated metal shell is corrosion resistance – even in harsh salt water environments
- OE on many major marine engine manufacturers
- Alumina ceramics for better heat transfer
- Triple seals prevent leakage
- Corrugated ribs prevent flashover
Includes 1 spark plug per package.
