The spark plug insulator is made of 99% pure alumina-silicate with a longer insulating nose to reduce fouling. This spark plug features a triple gasket sealing process that eliminates fuel leaks. It also contains a pure copper core that provides excellent heat dissipation and electrical conductivity.
