The NGK Copper V-Power spark plug box of 4 is built to improve ignitability versus standard nickel plugs using a V-cut center electrode and concave ground electrode for quicker starts and smoother idling. High-grade alumina ceramic insulator supports strong dielectric performance and heat transfer. Trivalent metal plating protects against corrosion and seizing, and the copper core helps remove heat for reliable OE-equivalent operation and longevity.
