BMW M3 G80 / M4 G82 Prepreg Dry Carbon Fiber Engine Cover

Engineered for BMW M3 G80 and M4 G82 owners, this Prepreg Dry Carbon Fiber Engine Cover is the premium carbon equivalent of the factory plastic cover that sits atop the S58 engine. It transforms the engine bay into a motorsport visual moment whenever the hood is opened, while shedding weight versus OEM. Manufactured in Europe and quality-controlled by BYC Performance, this BMW G80/G82 carbon engine cover matches OEM mounting geometry exactly.

If you're building a BMW M3 G80 tuning or M4 G82 modification project and want to extend the carbon language into the engine bay, this cover is one of the most visible engine-bay upgrades. Autoclave-cured prepreg carbon is noticeably lighter than the OEM plastic cover, with long-term UV resistance. Fits the entire S58-powered G-generation M family (M3 G80 473 hp, Competition 503 hp, CS 543 hp; M4 G82 Coupé all trims + CSL 543 hp).

Key Features

• Prepreg Dry Carbon Technology: Pre-impregnated plies cured in an autoclave under high heat and pressure.
• Direct OEM Replacement: Same clip and clamp geometry as the OEM S58 engine cover.
• Dual Profile Fit: One cover fits M3 G80 Sedan and M4 G82/G83 Coupé/Convertible engine bays.
• Weight Savings: Noticeably lighter than the OEM plastic cover.
• High-Temperature Resistance: Autoclave-cured resin retains dimensional stability at engine bay temperatures.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under a high-gloss UV-protective clear coat.
• Direct OEM Fit: Snaps onto OEM clip points. No drilling or modification required.

Prepreg Dry Carbon vs. Wet Carbon — Which Is Better?

Most aftermarket carbon parts use wet lay-up, where resin is hand-applied at room temperature — leaving voids and inconsistent weight. Prepreg dry carbon:

• Cured in an autoclave under high heat and pressure → a more consistent weave
• A controlled resin ratio → lighter and stronger
• The production method widely chosen in motorsport
• Minimal UV fading over years of use

Vehicle Fitment

This BMW G80/G82 carbon engine cover fits the following models:

• BMW M3 G80 Sedan (2021+) — S58 (473/503 hp)
• BMW M3 Touring G81 (2022+) — S58 (503 hp)
• BMW M3 CS G80 (2023+, limited) — S58 (543 hp)
• BMW M4 G82 Coupé (2021+) — S58 + Competition + CSL (543 hp)
• BMW M4 G83 Convertible (2021+) — S58 (503 hp)

NOTE: NOT compatible with M3 F80 / M4 F82 (previous generation, S55 engine) — the S55 engine cover has completely different geometry.

NOTE 2: BMW M2 G87 MAY be compatible since it shares the S58 engine, but the G87 cover trim may differ — please contact us before ordering.

FAQ

Does this fit both M3 G80 and M4 G82?
Yes. The S58 engine architecture is identical across the M3 G80 and M4 G82/G83 family; the cover fits every variant.

Does it affect engine performance?
No. The engine cover is a decorative bay trim — it has no direct impact on intake or cooling. It does provide weight savings.

Compatible with M3 CS, M4 CS, M4 CSL?
Yes. All G80/G82 trims share the same S58 engine cover geometry.

Compatible with M3/M4 F80/F82 (previous gen)?
No. F-generation uses the S55 engine with completely different cover geometry.

Compatible with M2 G87?
S58 engine is shared, but the G87 cover variant may differ. Contact us before ordering.

Will high engine temperatures damage the cover?
No. The autoclave-cured resin retains dimensional stability at high engine bay temperatures and is designed for engine bay conditions.
