The NGK V-Power spark plug improves ignitability over standard nickel plugs with a V-cut center electrode and concave ground electrode that speed spark development for quicker starts and smoother idle. High-grade alumina silicate ceramic insulates reliably, and a solid copper core helps dissipate heat. Trivalent metal plating reduces corrosion and seizing, while corrugated ribs and triple seals help prevent flashover and combustion leakage.
