The NGK Copper V-Power spark plug box of 4 boosts ignitability over standard nickel plugs through a V-cut center electrode and concave ground electrode that promote quicker starts and smoother idle. High-grade alumina silicate ceramic insulator provides improved dielectric strength and heat transfer, while trivalent metal plating reduces corrosion and seizing. A copper core assists heat removal and conductivity for reliable, OE-style replacement performance.
