NGK Racing Series Spark Plug
NGK Racing Series plugs are engineered to withstand the harshest engine conditions. Special insulator nose configurations improve throttle response, corrugated ribs prevent flashover, and a pure alumina silicate ceramic insulator provides superior strength and better heat transfer. The copper core aids in heat removal, while triple seals prevent leakage.
