BMW M135i F20 F21 Rear Diffuser Fins V2 in Matte Black
Transform the rear end of your BMW 1 Series M135i with these V2 rear diffuser fins, designed for the F20 and F21 chassis years 2011 to 2015. This simple stick-on diffuser fin kit adds a more aggressive, motorsport-inspired look without removing or replacing the factory diffuser. Finished in matte black, they integrate cleanly with the OEM rear bumper for a stealthy, factory-plus appearance.
We have used these ourselves and our customers love the quick visual upgrade and snug fit. If installed correctly, the included strong double-sided tape holds securely yet lets you peel the fins off later without marking the diffuser.
