Designed specifically for the A4 B9 factory rear bumper — and not compatible with the S4 — this diffuser adds a wider, more aggressive lower rear appearance with a deep gloss epoxy polished carbon black finish that showcases the natural carbon weave. At 130cm wide, the diffuser delivers comprehensive lower rear bumper coverage that visually lowers and widens the rear stance of the A4 B9 Sedan. Adhesive tape installation provides a clean, no-drill fitment with no permanent modification to the factory rear bumper.\n\u003c\/p\u003e\n\n\u003ch6\u003eFeatures:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine carbon fiber construction – autoclave cured and vacuum moulded using 3D design and CNC
