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. NGK spark plugs push the limits of performance and innovation, bringing the most advanced technology to today’s high-efficiency engines. From the high-tech Ruthenium HX™ to the industry standard OE-style spark plugs, NGK drives the future of spark plug engineering.
