The NGK Standard spark plug restores OE-level ignition reliability for everyday driving and regular service intervals. Packaged in NGK’s yellow box, it’s a proven replacement choice built to match original specifications. Featuring a high-grade alumina silicate ceramic insulator and a 98% copper core for heat dissipation, the plug also uses trivalent metal plating to resist corrosion and seizing, corrugated ribs to prevent flashover, and triple seals to prevent combustion leakage.
