Description Reviews This is a OEM MINI Cooper Coil Pack for all Gen 1 MINI's. This coil will fit all R50 and R52 MINI Cooper, and all R52 and R53 MINI Cooper S's. We find the most prominent issue with the ignition coil on these cars is the #3 coil plug rusts causing misfires, accompanied by an illuminated check engine light. Whether you're stock or tuned, the stock ignition coil is going to suit your needs, as it has proven itself to well over 300 horsepower. Many of the aftermarket “performance” coil packs come with incorrect size hardware and no isolator grommets, resulting in the end user puncturing/cracking the valve cover and causing an oil leak and a vacuum leak, requiring a new valve cover to be purchased. This is the best coil you can buy!
