FAQs
Will this rear diffuser fit my Audi A4 S4 4-Door?
It matches the rear bumper shown in the gallery for 2013-2015. Compare the valance shape in the photos with your own bumper first.
Is the carbon real?
Yes – carbon fiber with a UV-stable clear coat. Not a hydro-dipped or printed finish.
Do I need to cut the rear bumper?
No. It replaces the factory lower valance section and uses the original mounting points.
Can it be painted?
We would not recommend painting real carbon; the clear-coated weave is the finish.
Does it come with fittings?
The piece itself is supplied as shown; the factory fixings on your car are reused. Tape or sealant is recommended by most installers.
