BMW M5 F90 | Prepreg Dry Carbon Fiber Engine Cover Set

BMW M5 F90 Prepreg Dry Carbon Fiber Engine Cover Set

Engineered for BMW M5 F90 owners who want a premium engine bay finish, this Prepreg (Dry) Carbon Fiber Engine Cover Set replaces the OEM plastic covers over the S63 V8. Made to factory-spec mounting tolerances by leading manufacturers around the world and quality-controlled by BYC Performance, this BMW M5 F90 carbon engine cover set clips directly to OEM mounting points.

If you're building a serious BMW M5 F90 tuning project and want a high-impact visual upgrade every time you pop the hood, this dry carbon engine cover set is built for you. Autoclave-cured prepreg carbon fiber withstands V8 engine bay temperatures and resists UV fading. Engineered to complement the aggressive character of the S63B44T4-powered F90 M5, 600 hp standard and 617 hp Competition.

Key Features

• Prepreg (Dry) Carbon Technology: Pre-impregnated carbon plies cured in an autoclave under high heat and pressure ensure a consistent weave.
• Multi-Piece Set: Includes engine top covers, acoustic panel covers, and side covers as a complete set.
• Thermal Resistance: Autoclave-cured prepreg carbon does not deform under V8 engine bay heat.
• Weight Parity, Premium Look: Similar weight to OEM plastic covers but a dramatically more premium engine bay appearance.
• 2x2 Twill Carbon Weave: Authentic carbon fiber pattern under a high-gloss UV-protective clear coat.
• Direct OEM Fit: Plug & play installation on factory F90 M5 S63 engine cover clips.
• UV & Chemical Protection: Long-life clear coat protects against oil and fuel splash.

Prepreg (Dry) Carbon vs. Wet Carbon: Which Is Better?

Most aftermarket carbon parts are made using wet lay-up, where resin is applied by hand and cured at room temperature, leaving air 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
• Does not deform under engine bay temperatures

Installation Notes

Installing the BMW M5 F90 engine cover set is a direct OEM clip-on:

1. Park on a level surface and ensure the engine is cool.
2. Carefully lift the OEM plastic engine top covers (clip-attached).
3. Remove acoustic panel covers and side covers.
4. Press the new carbon pieces onto the same OEM clips.
5. Verify each cover seats fully and does not shift on the engine.

Care & Maintenance

Wipe with a soft damp cloth. Clean oil or fuel splash promptly. Avoid direct pressure-washer jets into the engine bay.
