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 plugs offer reliable performance and improved ignitability over standard nickel plugs. Actual OE or equivalent replacement spark plug.
