NGK V-Power spark plugs offer economical performance for nearly any automotive application—and they're the only plugs with NGK's V-Groove technology. These plugs enhance ignitability, lower the voltage requirements of ignition systems, and have strong anti-fouling characteristics, while improving fuel mileage and acceleration performance.

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

NGK racing plugs feature special electrode materials—precious metals like platinum, iridium, and ruthenium—for greater durability and low voltage requirements. Fine-wire center and ground electrodes provide better sparking and enhanced ignitability. And, the unique arrangement of insulator noses improves throttle response!
