The NGK Laser Platinum spark plug delivers improved ignitability and longer service life compared with conventional nickel plugs. Laser-welded dual platinum surfaces slow wear for stable idling and superior anti-fouling, while high-grade alumina ceramic and a 98% copper core help control operating temperature. Many designs include a platinum pad on the ground electrode for even wear in distributorless ignition systems.
