3951 Spark Plug NGK TR55

Description V-Power Spark Plug (NGK)– Designed to operate over a much wider heat range than ordinary plugs– Resists carbon build-up 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– Greater ignitibility and performance over conventional spark plugs– Trivalent metal plating has superior anti-corrosion and anti-seizing properties– Highly durable against electrical and chemical wear, making them long-life replacement plugs– Spark occurs at the edge of the center electrode- so heat is not absorbed by the electrode itself allowing the flame kernel to expand quickly and efficiently for a complete burn and great performance– Tapered Seat– Thread: 14mm– Reach: .691″– Projected Tip– Resistor– Manufacturer Heat Range: 5K Ohm– Electrode Core Material: Copper– Electrode Tip Material: Nickel Alloy– Wrench Diameter: 5/8″– Ground Strap Quantity: One
