The NGK Standard BR4-LM spark plug is a proven OE-equivalent replacement built for dependable, everyday operation. It uses a high-grade alumina silicate ceramic insulator for strength and dielectric performance, a solid copper core for efficient heat dissipation, and triple-gasket sealing to prevent combustion leaks. Trivalent metal plating improves anti-corrosion and anti-seize properties for easier installation and reliable long-term service.
