Why NGK Iridium? 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, new metal shell plating process for better anti-corrosion. NGK Iridium One Step Colder plugs are recommended for cars with heavy modifications. These NGK Iridium plugs will get your Cooper S running smoother and free up some power through increased efficiency and increased heat resistance.
Please Note: NGK Iridium plugs are able to use larger gap setting with less voltage. Some customers choose to regap these plugs to correct misfiring or tune for optimal spark -- do so at your own risk -- slide-type plug gapper will damage the fragile Iridium tip.
