Quick Overview

Iridium Spark Plug

Iridium Spark Plug

Six times harder than platinum, iridium withstands temperatures up to 4,000°F
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
