Show original supplier description
The BMW M Performance Rear Diffuser is a genuine OEM accessory specifically engineered for the F22/F23 2 Series, fitting M235i and M240i models. It is manufactured using a pur-rim (polyurethane reaction injected molding) process, ensuring a durable yet lightweight construction. The diffuser features a matte black finish, providing a sleek, aggressive look, and is also paintable to match your vehicle's custom scheme. Installation of this rear diffuser requires the M Sport aero package/bumper to be already present on the vehicle. Furthermore, vehicles equipped with a standard exhaust system will need additional exhaust tip adapters and new stainless steel or carbon fiber exhaust tips, which are sold separately. Models with the M Performance Exhaust system can utilize the diffuser without the need for these additional components. This part is designed to enhance the aerodynamic profile and sporty appearance of compatible BMW 2 Series vehicles.
