NGK V-Power spark plug (box of 4) improves ignitability with a v-cut nickel alloy center electrode and a concave ground electrode that directs the spark for quicker starts and smoother idle. High-grade alumina silicate ceramic insulator enhances dielectric performance while a copper core helps control operating temperature. Trivalent plating and triple seals help resist corrosion and ensure easier installation and removal.
