Features
- 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 large volume area for the flame's center
