The NGK V-Power spark plug, packaged in a box of 4, improves spark development with a V-cut center electrode and concave ground electrode that direct the spark toward the edge for faster ignitability. High-grade alumina silicate insulator and trivalent metal plating enhance dielectric performance and resist corrosion, while the copper core helps remove heat for reliable starts and a smoother idle compared with standard plugs.
