The NGK V-Power spark plug is an OE-equivalent unit designed to increase ignitability and improve idle smoothness. Its V-cut center electrode and concave ground electrode focus the spark for faster development and reduced quenching. A high-grade alumina silicate ceramic insulator supports dielectric performance, while trivalent metal plating prevents corrosion and seizing. Corrugated ribs, copper core and triple seals contribute to heat management and flashover protection.
