Add a refined aerodynamic detail to the roofline and boot lid of your Audi A4 B9 S-Line or S4 Sedan with this genuine carbon fiber boot spoiler, produced using CNC machining and vacuum moulding with a high-gloss epoxy surface finish. Designed specifically for the A4 B9 and S4 Sedan 4-door body, this single deck boot spoiler complements the factory body lines with a subtle yet purposeful visual upgrade that elevates the rear profile without an overly aggressive appearance.
