Iridium spark plugs are more durable and have a higher melting point compared to platinum plugs. 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.
