- Finishes the front end when you're already running a carbon lip and grilles
This is a finishing part, and it's honest to say so. If your bumper is still factory everywhere else, ducts alone won't transform the car.
But once you have a carbon lip and carbon grilles on a G8X, the stock plastic ducts are the last painted-black element left in the bumper, and they start to stand out. The single-slat MP profile cleans up the opening and gives the whole front end one consistent material. That's why these almost always sell alongside a lip or a grille set rather than on their own.
Solid dry carbon, matched pair, clips into the factory locations.
G80 M3 (2021+) · G82 M4 (2021+) · G83 M4 Convertible (2021+). Competition and xDrive included. Compatible with factory bumper only.

Answers
Frequently asked
- Dry carbon starts as pre-preg sheet — the resin is already in the fibre in an exact ratio, then cured under pressure in an autoclave. There is no excess resin, so the part is lighter, stiffer and the weave stays perfectly straight.
- Every mould is test-fitted on a real vehicle before it goes into production, and each product page lists exact chassis, trim and pre/post-LCI fitment. If a part does not fit as described, we cover return shipping.
- Free shipping on every order, arriving in 6-8 business days. You will get tracking as soon as it ships.
- Trim, mirror caps and interior parts are straightforward DIY jobs with the included hardware and guide. For front lips, diffusers and spoilers we recommend a professional installer.
- Yes. Every part gets a UV-inhibited clear coat, gloss or satin, so the weave does not yellow or bloom after sun exposure.
- 30 days on uninstalled parts in original packaging, refunded to your original payment method, plus a 2-year warranty against delamination and clear-coat failure.
