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.
