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.

NGK's OE CERAMIC TECHNOLOGY: High grade alumina silicate ceramic creates a stronger insulator for optimal dielectric performance; SOLID COPPER CORE: 98% pure copper core offers superior heat dissipation, conductivity and ultra wide heat ranges; COLD-ROLLED THREADS: Prevents cross-threading and damage to cylinder heads

This item has been discontinued. Surface gap plugs are nearly immune to pre-ignition, and usually require a special high energy ignition system. They can be susceptible to fouling, especially in colder applications, but may be necessary in high compression applications. Sorry, no automotive applications are associated with this part.
