The NGK V-Power spark plug, offered in a box of 4, increases ignitability with a V-cut center electrode and concave ground electrode that focus the spark toward the edge for faster development. Pure alumina silicate insulation supports reliable dielectric performance while trivalent metal plating resists corrosion and seizing. A copper core assists heat removal, contributing to dependable starts and smoother idling compared with standard plugs.
