Six times harder than platinum, iridium doesnt melt in temperatures up to 4,000F. Because the iridium electrodes of these plugs can 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
