Six times harder than platinum, iridium doesn't melt in temperatures up to 4,000 degrees Fahrenheit
Because the iridium electrodes of these plugs can be shrunk to only 0.4mm, voltage requirements decrease while firing performance improves
360 degree 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 flame's center
