E46 M3 Rear Diffuser
This diffuser has been designed to offer increased performance on both the race track and the street. We took special care to ensure that no air will get between the diffuser and the underside of the car, setting it apart from others on the market. The diffuser is cut with a water jet, powder coated black, and comes with all required hardware. MADE IN THE USA
Does not fit Non-M3 rear bumpers.
