Description

Nothing shows off a car’s performance potential like striking visual upgrades with an aggressive twist. The factory rear diffuser on the pre-facelift B9 S4 leaves something to be desired in that department, which is why we set out to produce an affordable, attractive, and motorsport-inspired improvement for the rear lower section with our rear diffuser! This new Gloss Black Rear Diffuser follows the factory lines and accentuates the performance nature of your B9 S4 while staying affordable thanks to its vacuum-formed plastic construction.
