Spark plug with 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. Designed to operate over a much wider heat range than ordinary plugs. Resists carbon buildup and pre-ignition.
