NGK V-Power plugs feature a unique v-cut in the center electrode that directs the spark to the edge of the electrode, helping the spark develop more rapidly, increasing ignitability and reducing quenching. Trivalent metal plating provides superior anti-corrosion and anti-seizing properties Corrugated ribs prevent flashover Pure alumina silicate ceramic insulator, provides superior strength and better heat transfer Copper core aids in heat removal Triple seals prevent leakage Recommended in mid-high level boosted applications and 300 nitrous shots ShellThread Diameter - 14mmThread Pitch - 1.25mmSeat Type - TaperedReach - 18mm (.709")Hex Size - 5/8" (16mm)Terminal Type - SolidOverall Height - ISOGap - .028" (0.7mm) Center ElectrodeMaterial - NickelType - V-CutSize - 2.5mmProjection - Non-Projected Ground ElectrodeMaterial - NickelType - StandardQuantity - 1 SpecificationsResistor - YesResistor Value - 5k OhmHeat Range - 7Torque Specs - Cast Iron: 10.8-18 lb. ft.
