These NGK V-Power spark plugs offer economical performance for nearly any automotive application and are the only plugs with NGK's V-Groove technology. They 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.

Good enough for standard gasoline, but short life for high octane number gas

Work great. Lots of Vette folks use these on their stock to simple bolt-on Vettes with no issues.

Spark plugs for my Mach 1

Summit RacingSummit Racing Verified Purchase

Shipping was rediculously fast! These new NGK V-Power spark plugs made a world of difference on my 2003 Mach 1. The throttle response is way better now! I highly recommend these for Mach 1's and Cobras.
