Six times harder than platinum, iridium doesnt melt in temperatures up to 4,000F
Because the iridium electrodes of these plugs be shrunk to only 0.4mm, voltage requirements decrease while firing performance improves
360 laser welding of electrode provides a seal that resists wear even in the worst conditions
Ground electrode features a tapered cut and U-groove that form a large volume area for the flames center
