MINIUSA has released officially approved blue ignition wires for both the Cooper and Cooper S. Here’s all the info from the official release:

The wires are made of stainless steel magnetic conductive winding. The cables have a blue silicon-over-silicon wire insulation for superior voltage and temperature protection. The spark plug and coil boots are 100% identical to the original equipment and are also made of silicone.

To ensure that there is no interference with the radio or other electronic components of the car, the cables match the resistance of the original MINI spark wires.

MF Analysis: I suppose $40 for a little eye candy under the hood isn’t that bad.
