NGK SPARK PLUG

The ultimate in the evolution of spark plug technology and performance from the industry leader The iridium electrode is 25% smaller than a platinum electrode, and it’s just 1/4 the size of a conventional nickel electrode Ultra-small-diameter center electrode reduces voltage requirement and extends ignition system life New metal shell plating has enhanced anticorrosion qualities

NGK (7901) Spark Plug, IJR7A9: 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
