NGK (4043) ZFR4F-11 V-Power Spark Plug

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 45 degree V-Power center electrode increases anti-fouling characteristics and performance Increased fuel economy and lower emissions Lowers ignition system voltage requirements Greater ignitability and performance over conventional spark plugs Trivalent metal plating has superior anti-corrosion and anti-seizing properties
