The Audi A4 B9 Avant blends performance and practicality — but the rear end deserves the same aggressive attention as the front. This carbon fiber rear diffuser extension is designed to enhance the lower bumper profile, adding sharper definition and a more performance-inspired finish to your Avant build.
Precision engineered using advanced molding techniques, this rear lip follows the factory bumper lines for a clean OEM+ appearance while giving the car a lower, wider visual stance. The gloss carbon finish contrasts perfectly against factory paint and ties in seamlessly with other aero upgrades.
