Iridium plugs are more durable and have a higher melting point compared to Platinum. Enjoy the benefits of reduced corrosion, improved ignition, superior anti-fouling, and a lower required voltage. These NGK plugs will get you running smoother and making more power through increased efficiency and increased heat resistance.
- Note:
- Iridium plugs are able to use larger gap setting with less voltage. Some customers choose to re-gap these plugs to correct misfiring or tune for optimal spark - do so at your own risk - a slide-type plug gapper can damage the fragile iridium tip.
- FITMENT:
- Mitsubishi Evolution 8 2003-2005 ONLY (DOES NOT FIT EVOLUTION 9)
