Laser welded iridium center electrode tip ensures high durability and higher spark. A platinum disc welded to the back of the earth electrode has a long service life. A longer insulating nose prevents contamination, wavy ribs on the insulator prevent flashover, and a triple gasket seal eliminates combustion gas leaks. Faster starts and acceleration Trivalent metal plating for improved fuel economy and lower emissions, superior corrosion and seizing resistance.

Laser Iridium spark plugs offer superior ignition performance and long life. The smallest tip diameter iridium/platinum surface available ensures stable idle, superior fouling resistance, 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 has a long service life. The long nose of the insulator prevents dirt, the wavy ribs of the insulator prevent flashover, and the triple gasket seal prevents combustion gas leaks. Faster starts and faster acceleration. Improved fuel efficiency and reduced emissions, trivalent metal plating provides excellent corrosion and seizure resistance.
