Laser welded iridium center electrode tip ensures high durability and excellent spark. The platinum disc is welded to the back of the ground electrode for long life. A long insulating nose prevents dirt, wavy ribs on the insulator prevent flashover, and a triple gasket seal prevents combustion gas leaks. Faster starts and faster acceleration. Excellent fuel efficiency and low emissions, trivalent metal plating provides excellent corrosion and fire resistance.

Laser Iridium spark plugs offer superior ignition performance and long life. The smallest tip diameter iridium/platinum surface ensures low speed wear rates, providing stable idle, excellent anti-fouling, improved fuel economy and reduced emissions.
