The NGK Traditional spark plug box of 4 is an OE-equivalent nickel alloy replacement built for reliable ignitability and long service life. It employs a high-grade alumina silicate ceramic insulator for strong dielectric performance and triple gasket sealing to prevent combustion gas leakage. A solid copper core aids heat removal and conductivity while trivalent metal plating offers anti-corrosion and anti-seizing protection for easier installation and removal.
