Laser welded iridium center electrode tip provides high durability and superior spark. A platinum disc welded to the back of the ground electrode has a long service life. The long insulator nose prevents carbonization, the wavy ribs on the insulator prevent flashover, and the triple gasket seal eliminates combustion gas leaks. Faster starts and faster acceleration. Trivalent metal plating for excellent fuel economy and low emissions, excellent corrosion resistance and anti-seize.

Laser Iridium spark plugs offer superior ignition performance and long life. The iridium/platinum surface with the smallest tip diameter ensures stable idle conditions, excellent corrosion resistance, and low wear rates for improved fuel economy and reduced emissions. Laser welded iridium center electrode tip ensures high durability and larger spark. A platinum disc welded to the back of the ground electrode provides long life. The long insulator nose prevents carbonization, the wavy ribs on the insulator prevent flashover, and the triple gasket seal eliminates combustion gas leaks. Faster starts and faster acceleration. Trivalent metal plating for excellent fuel economy and low emissions, excellent corrosion resistance and anti-seize.
