NGK Iridium offer more durability and a higher melting point compared to platinum, better center electrode anti-oxidation and anti-erosion, improved ignition, superior anti-fouling, lower required voltage, and a new metal shell plating process for better anti-corrosion. One Step Colder plugs are recommended for cars with heavy modifications. These NGK plugs will get running smoother with more power through increased efficiency and 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.
