Connor Phillips –
Really good quality diffuser. Bought it for my AUDI RS4 B9 & B9.5 and it looks brilliant. One edge needed a tiny bit of persuasion but that is minor. Overall very impressed and I would recommend CT Carbon.
Tyler Brooks –
It is a good diffuser for the AUDI RS4 B9 & B9.5 but not perfect. The fitment on one side is slightly off and there is a tiny bubble in the lacquer on one corner. CT Carbon offered to help when I raised it, which was good of them.
Aiden Turner –
Pretty impressed with this diffuser. It looks fantastic on the AUDI RS4 B9 & B9.5 and the quality is clearly better than budget alternatives. Minor deduction for a slight imperfection near one fixing point, but it is barely visible fitted.
Scott Reynolds –
Love this diffuser for my AUDI RS4 B9 & B9.5. The gloss finish is mirror-quality and the carbon weave is consistent all the way to the edges. Took about 30 minutes to fit with basic tools. Would absolutely order again.
Noah Evans –
Good diffuser, looks great on the AUDI RS4 B9 & B9.5. Quality is noticeably better than some cheaper alternatives I have seen online. Shipping was about a week which is fine for a free service. Would order from CT Carbon again.
Mike Anderson –
Proper OEM-quality diffuser for the AUDI RS4 B9 & B9.5. No drilling, no modification, bolted straight on. Looks incredible and completely transforms the car. CT Carbon really know their stuff.
Nathan Wright –
Bought this diffuser for my AUDI RS4 B9 & B9.5 after seeing it recommended on a forum and I’m not disappointed. Quality is exceptional — real pre-preg carbon, not a cheap overlay. Will be ordering more parts.
Alex Carter –
Good quality diffuser for the AUDI RS4 B9 & B9.5. Took a bit of fiddling to get aligned perfectly but once it was on it looks great. Minor issue with one clip but overall very happy — good value for money.
Matt Collins –
Just fitted the diffuser to my AUDI RS4 B9 & B9.5 — absolutely transforms the look. Real carbon, not a wrap, and the difference in quality is obvious. Zero fitment issues. Free US shipping was a bonus I didn’t expect.

The diffuser arrived quickly and fits my AUDI RS4 B9 & B9.5 perfectly. Solid carbon quality — you can feel the difference compared to cheaper alternatives. Highly recommend CT Carbon Kits.
