2430 V-Power Resistor Spark Plugs - CR4HS

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. Features Lowers ignition system voltage requirements. Greater ignitability and performance over conventional spark plugs. Trivalent metal plating has superior anti-corrosion and anti-seizing properties. Increased fuel economy and lower emissions. Highly durable against electrical and chemical wear. Performance spark plug. Specifications Dimension: 0.88 in H x 0.79 in W x 3.23 in L. Weight: 0.12.
