NGK V-Power spark plug improves ignitability through a V-cut center electrode that encourages faster spark development and reduces quenching for smoother idle and quicker starts. Built to OE standards, it uses a high-grade alumina insulator and trivalent metal plating for corrosion resistance and easier removal. A copper core helps dissipate heat, making these plugs a practical upgrade over conventional nickel types.
