The NGK V-Power spark plug provides improved ignitability for OE-style applications via a V-cut center electrode and concave ground electrode that help the spark develop more rapidly. Constructed with high-grade alumina-silicate ceramic for a strong insulator and trivalent metal plating to resist corrosion and seizing, these plugs aim for easier installation, quicker starts and smoother idle while maintaining OE replacement reliability.
