The NGK V-Power spark plug is an OE-style upgrade focused on improved ignitability and smoother idle. Its specially V-cut center electrode and concave ground electrode help the spark develop more rapidly for quicker starts. NGK’s alumina silicate ceramic insulator and a copper core enhance dielectric performance and heat removal. Trivalent metal plating protects against corrosion and seizing, while the electrode geometry reduces quenching and supports more reliable combustion.
