Purchased used a few months back. During the course of troubleshooting a misfire (waiting for spark plugs now) I pulled my ignition coils and one of these kids is not like the other. Then this morning I snagged 4 from a pick-your-part yard. Mine: 2013 Roadster S Pick: 2012 Cooper S The top row are the ones I picked from the yard (2012 S) The bottom row (with the mismatched 1) is from my vehicle (2013 S) Other than the top are Bosche the others are Delphi, anyone know the differences? Can I use the Bosch? belay, believe I figured it out. One of them are performance coils the other standard.
