Laser welded Platinum center electrode tip creates faster starts and quicker acceleration while the platinum disc welded to backside of ground electrode provides long life

Trivalent metal plating provides superior anti-corrosion and anti-seizing properties

Triple gasket seal eliminates combustion gas leakage

NGK Spark Plugs are designed to operate over a much wider heat range than ordinary plugs. They resist carbon buildup and pre-ignition. Each features high alumina ceramics for better heat transfer and electrical insulation. A patented triple gasket sealing process eliminates the possibility of combustion gas leakage, and a longer insulator nose prevents fouling and misfiring. A solid copper core and its nickel tipped electrode provide a longer plus life.
