WHY THE CARBON FIBER DIFFUSER?

The carbon fiber rear diffuser is one of the best exterior upgrades for the B9 Audi A5 S-Line and S5, giving the rear end a more aggressive, motorsport-inspired appearance while enhancing the factory body lines. Its sculpted aerodynamic design adds depth and a more performance-focused look, creating a sharper and more refined rear profile. Constructed from premium carbon fiber, it delivers lightweight strength, exceptional durability, and a high-end finish that perfectly complements Audi’s styling. Designed specifically for the B9 A5 with the S-Line package and the B9 S5, this diffuser does NOT fit the RS5. Finished with a UV-resistant clear coat, it is built to resist fading, yellowing, and discoloration, ensuring long-lasting gloss and a premium appearance.
