BMW G82/G83 M4 Engine Bay Parts
12 products
These G82 M4 engine bay parts protect the S58 as much as they dress it. Two guards shield the front-mounted oil cooler, one in aluminum and one in carbon, and a CSL-style brace ties the shock towers together.
For looks there are two carbon engine covers, a cooling shroud, ECU, headlamp and cap covers and a cowl top grill, plus Unit 17's dry carbon intake. Every part is listed for the G82 coupe and the G83 convertible alike, and they're the same listings as on the G80 M3 engine bay page.
BMW G82/G83 M4 Engine Bay Parts buying guide
Oil cooler guard for the G82 M4 engine bay: aluminum or carbon
On the S58 the oil cooler is mounted at the front, in a spot where rocks, road debris and loose hardware can reach it. A hit there can mean a costly repair, so a guard is worth fitting before the car sees a gravel road or a track day.
- Unit17 aluminum guard: high-strength aluminum with slit-style cutouts, shaped to keep air reaching the cooler while stopping debris. The installation hardware is in the box.
- Carbon oil cooler guard: a pre-preg dry carbon skid plate in glossy or matte finish, for owners who want the underside to match carbon elsewhere.
For an M4 that's driven hard or often, the aluminum guard is the one designed around protection. The carbon plate makes sense when matching the rest of the car's carbon matters more.
Covers and trim you see with the hood open
The carbon engine cover comes in the OEM style or the Xtra Wide design, both in gloss or matte pre-preg; the Xtra Wide is the wider of the two. Around it you can add the 3x3 twill cooling shroud (self-tapping screws included), the ECU cover that reuses the factory grommets, and the cap set, which sits over the plastic caps on 3M tape. The headlamp cover's model menu lists G82 and G83 separately, so choose the body you drive. The cowl top grill is for left-hand-drive cars. A Coming soon listing will sell covers singly or as a set; its model menu offers G80 G82 or G87, and M4 owners choose the first.
Strut brace and intake
The CSL-style strut brace is listed for 2021-on M4 coupes and convertibles. It bolts to the OEM mounting points, and its listing says it cuts chassis flex under hard cornering for sharper steering response. The dry carbon intake is a Unit 17 exclusive with high-flow filters, sold as a bolt-on. Before you fit anything, test it on the car: if a part doesn't fit the M4 named on its product page, contact us first, and our fitment guarantee covers the return shipping.
Frequently asked questions
Do engine bay parts differ between the M4 coupe and convertible?
No. Every listing on this page names the G82 coupe and the G83 convertible together, because both use the S58 engine. The only place the body style comes up is the headlamp cover, whose model menu lists G82 and G83 as separate entries, so pick the one that matches your car.
Does an oil cooler guard cut airflow to the cooler?
The aluminum guard is designed not to. Its listing describes slit-style cutouts that let air through while keeping debris out, with the aim of protecting the cooler without giving up cooling. The carbon skid plate's listing doesn't describe its airflow, so compare the photos, or text 609-525-4865 if you'd like help choosing.
Which option do I pick on the Coming soon engine bay set for an M4?
Choose G80 G82 in its model menu (the other choice is G87), then either the full set or a single piece: OEM engine cover, air intake cover, cowl grill with carbon mesh, electrical cover, coolant shroud or headlamp cover, in glossy, matte or forged. The listing's title names the G83 too. It has no ship date yet, so ask us before planning around it.
Is the dry carbon intake made by Unit 17?
Yes. It's a Unit 17 exclusive design, listed for the G82 and G83 M4 from 2021 as well as the M3 and M2. It's a complete intake set with high-flow filters and an open design, described as a bolt-on that improves airflow and throttle response and brings out more of the turbo sound.
