The NGK V-Power spark plug delivers improved ignitability over conventional nickel plugs thanks to a V-cut center electrode and concave ground electrode that speed spark development. High-grade alumina silicate ceramic strengthens insulation and dielectric performance, while trivalent plating protects against corrosion and seizing. A copper core aids heat dissipation and corrugated ribs reduce flashover for dependable starting and smoother idle.
