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

High temp silicone outer cable jacket resists underhood temperatures up to 250 degrees C. High density premium fiberglass reinforced braiding over EPDM/silicone inner isulation for superior dielectric strength and excellent cable tensile strength. Stainless steel terminals. Silicone seal at spark plug boot.
