Description

NGK Pro-V spark plugs offer reliable performance and improved ignitability over standard nickel plugs. Engineered specifically small engine applications, the special V-cut nickel alloy center electrode and concave ground electrode of NGK's Pro-V 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 and prevents spark plug overheating. Trivalent metal plating ensures superior anti-corrosion and anti-seizing properties.
