NGK Iridium Plug
Laser welded Iridium center electrode tip ensures high durability and greater spark
Platinum disc welded to backside of ground electrode provides long life
Longer insulator nose prevents fouling, corrugated ribs on insulator prevents flashover, and the triple gasket seal eliminates combustion gas leakage
Faster starts and quicker acceleration
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.
