Original equipment manufacturer approved and an excellent upgrade from standard spark plugs, NGK V-Power spark plugs feature a special V-Groove center electrode and concave ground electrode to increase ignitibility by causing the spark to occur between the edges of the center electrode and ground electrode. The V-Groove center electrode also allows for more area for flame expansion. Trivalent metal plating has superior anti-corrosion and anti-seizing properties.
