The NGK Standard spark plug is an OE-equivalent nickel-alloy replacement that prioritizes dependable starts and long service life. High-grade alumina silicate ceramic delivers strong insulation and dielectric performance, while a solid copper core aids heat dissipation. Triple seals prevent combustion leakage and trivalent metal plating offers corrosion and anti-seize protection for easier installation and removal, with corrugated ribs to reduce flashover.
