BMW G82/G83 M4 Bumper Trims & Exterior Details
7 products
Carbon trim for the G82 M4 front bumper and a handful of small covers, for the coupe and the G83 convertible alike.
The bumper parts are a pair of lower air ducts and a panel that hides the crash foam behind an open grille. They're the same listings as on the G80 M3 bumper trims page, because the M4 wears the M3's front fascia. The rest are headlamp covers, fuel cap and antenna covers, and headlight delete panels for cars that only see the track or a show floor.
BMW G82/G83 M4 Bumper Trims & Exterior Details buying guide
G82 M4 front bumper: air ducts and foam cover
Both bumper pieces are pre-preg dry carbon. The lower air duct pair replaces the factory ducts at the bottom of the bumper, left and right. If you prefer a different design there, the dual air duct sits on the G82 M4 vent trims page; plan on the bumper coming off for that one, as its listing explains.
The crash foam cover matters most on an M4 with an open-slat aftermarket grille, because the wider gaps can leave the black foam in the nose on show. It comes in glossy, matte or forged carbon. Some makers design their foam covers around specific grilles, and our listing doesn't say which grilles it has been paired with, so name yours when you order or text 609-525-4865. Grille choices for the coupe and convertible are under G82 M4 grilles.
Headlight parts after the 2025 update
BMW fitted the M4 with new headlights and taillights for 2025. Two parts here relate to the headlights, and each is sold in a single version for 2021-on cars: the headlight delete panels, which replace the light units and are meant for off-road, track and show use only, and the headlamp cover, in gloss or matte with a model option to select. On an LCI M4, ask us to confirm either one before you buy.
Fuel cap and antenna covers
There are two dry carbon fuel cap covers, and one is offered in gloss, matte or forged carbon, which helps if you're matching another part on the car. The antenna cover has LCI and pre-LCI versions, and the G83 convertible is named on its listing. A photo of your antenna tells us which version you need.
The M4 has its own rear corners, listed with the M4 diffusers. Before anything goes on for good, test-fit it. An unfitted part in its original packaging can come back within 14 days of delivery. A part that doesn't match the M4 named on its listing is covered by our fitment guarantee, which pays the return shipping as long as you contact us before installing.
Frequently asked questions
Do these trims fit the G83 M4 convertible?
Yes. Every part on this page has a fitment line for the G82/G83 M4 from 2021 on, so the coupe and the convertible choose from the same list. The antenna cover's listing also names the G83 convertible. If you're unsure about a part for your car, text a photo to 609-525-4865.
Why would an M4 need a crash foam cover?
Only if the foam shows. The front bumper holds a block of crash foam behind the kidney grille, and an open-slat aftermarket grille leaves gaps where it can be seen. The cover puts dry carbon in that space instead. Choose glossy, matte or forged carbon to suit the grille and splitter you already run.
Is the M4 air duct pair different from the M3 version?
No, it's one listing for both cars. The pair is marked for the G80 M3 and the G82/G83 M4 because they share a front fascia. Rear bumper parts are a different story: the M4's rear corners are M4-specific, which is why they're sold separately with the diffusers.
Which fuel cap cover should I choose for my M4?
Both are dry carbon covers listed for the M4 and several other M cars, from the E9X M3 to the G87 M2. One comes in a single finish. The other lets you pick gloss, matte or forged carbon, which is handy if you're matching a forged or matte part elsewhere on the car. Compare the photos on each listing.
