Transform the rear profile of your 2012-2016 Audi A5 B8.5 Non-SLine with this genuine S5-spec rear diffuser. Manufactured from reinforced ABS polymer, it installs using existing bumper mounting points – zero body modification needed. The vertical fins redirect exhaust gases away from the undercarriage, decreasing drag by 8% (verified in CFD simulations) and reducing rear-wheel dust accumulation.
Unlike universal diffusers, this unit maintains factory exhaust clearance for both single/dual-pipe configurations. Textured matte black finish matches OEM trim, while the 3D-molded channels amplify the sportier stance of S-line models. Compatibility includes all coupe, cabriolet, and Sportback variants within the B8.5 generation.
