Why choose NGK Iridium IX for your MINI Cooper? The Iridium IX have 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.
The NGK Iridium IX is a single electrode plug and is available in both standard heat range for a stock Gen 1 MINI Cooper as well as a set colder range plug for a modified R52/R53 MINI Cooper S. The "cooler" plugs work great installed with a Supercharger Pulley on a Gen 1 MINI Cooper S. These "cooler" NGK plugs will get running smoother with more power through increased efficiency and heat resistance. All plugs come pre-gapped, but should be checked for .035" gap before installation. This is a great upgrade for any Gen 1 MINI Cooper!

R50 2002-2006 Hatchback Cooper
