NGK SPARK PLUGS SPARK PLUG #4421/10

NGK V-Power plugs feature a unique v-cut in the center electrode that directs the spark to the edge of the electrode, helping the spark develop more rapidly, increasing ignitability and reducing quenching. NGK V-Power spark plugs offer reliable performance and improved ignitability over standard nickel plugs. Engineered specifically for OE applications, the special V-cut nickel alloy center electrode and concave ground electrode of NGK's V-Power spark plug increases ignitability providing quicker starts and smoother idle. NGK's legendary high grade alumina silicate ceramic creates a stronger insulator for optimal dielectric performance. Trivalent metal plating ensures superior anti-corrosion and anti-seizing properties. NGK V-Power Spark Plug.
