NGK V-Power Spark Plugs

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. The V-Power plugs are also highly durable against electrical and chemical wear, making them long-life replacement plugs.

Because of the V-Groove, the spark occurs at the edge of the center electrode—so heat is not absorbed by the electrode itself. This allows the flame kernel to expand quickly and efficiently for a complete burn and great performance. More than a hundred models are available, both universal and application-specific; order the plugs designed for fitment on your vehicle.
