Genuine BMW M Performance Rear Diffuser.
This rear diffuser has been designed to perfectly fit 428i vehicles. The diffuser is constructed using a PUR-RIM (Polyurethane Reaction Injected Molding) process that makes it both strong and lightweight. The diffuser comes in a black matte finish and can be painted if desired. (Installed pictures show part of the diffuser painted, uninstalled picture is how the diffuser will look when unpackaged.)
Note: Installed pictures show dual exhaust cutouts. This item only features single exhaust cutout, as shown in the un-installed picture. This product can only be installed on vehicles with the M Sport package. Not compatible with towing hitch or rear carrier.
