Designed to operate over a much wider heat range than ordinary plugs

Resists carbon buildup and pre-ignition

High alumina ceramics for better heat transfer and electrical insulation

Solid copper core and nickel tipped electrode provide a longer plus life

Patented triple gasket sealing process eliminates the possibility of combustion gas leakage

Fine-wire center and ground electrodes provide better sparking and enhanced ignitability

Made to withstand the severe conditions that occur in racing engines

Zinc dipped shell prevents corrosion while the triple gasket seal eliminates combustion gas leakage

Special configurations are used for the insulator noses to improve throttle response and prevent fouling with corrugated ribs on insulator to prevent flashover

Solid copper core for greater spark
