Description Reviews MINI Cooper 550 Injectors w/ Harness & My Genius Tuner Box w/ Cords. The injectors have about 300-500 miles on them and work as they should. The My Genius Box was married to another car and might need to be reset. Revolution MINI should be able to do that for you if you use them to tune your car, or any other Tuner that uses that platform. Do all necessary research before ordering as this is not eligible for return.
