Big performance in a little package. 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 requirement of ignition systems, and have strong anti-fouling characteristics, while improving fuel mileage and acceleration performance. The V-Power plugs also are highly durable against electrical and chemical wear, making them a long-life replacement plug. 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.
