BMW M5 F90 | Prepreg Dry Carbon Fiber 3D Vented Hood

BMW M5 F90 Prepreg Dry Carbon Fiber 3D Vented Hood

Engineered for BMW M5 F90 owners who demand a high-quality finish, this Prepreg (Dry) Carbon Fiber 3D Vented Hood transforms the front of your sedan with aggressive race-hood character while helping evacuate heat from the engine bay. Made to factory-spec mounting tolerances by leading manufacturers around the world and quality-controlled by BYC Performance, this BMW M5 F90 carbon 3D vented hood bolts directly to OEM hinges and latches.

If you're building a serious BMW M5 F90 tuning project and need a part that exceeds the factory steel hood in both performance and finish, this dry carbon 3D vented hood is built for you. Autoclave-cured prepreg carbon fiber is noticeably lighter than the factory steel hood, more structurally consistent, and offers outstanding long-term UV resistance. Engineered to match the aggressive character of the S63B44T4-powered F90 M5, 600 hp standard and 617 hp Competition, this hood is the ideal aesthetic and functional upgrade.

Key Features

• Prepreg (Dry) Carbon Technology: Pre-impregnated carbon plies cured in an autoclave under high heat and pressure ensure homogeneous resin distribution and a consistent weave.
• 3D Vented Design: Functional vents on the upper surface evacuate hot air from the engine bay, lowering S63 V8 bay temperatures.
• Significant Weight Reduction: Noticeably lighter than the OEM steel hood. Reduces front axle weight, improving balance and steering feel.
• Race-Grade Strength: Carbon fiber offers very high strength for its weight.
• 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 (pre-LCI) hinges, latch, insulation, and gas strut mounting points.
• UV & Chemical Protection: Long-life clear coat protects against fading, cracking, fuel splash, and road tar.

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
• Minimal UV fading over years of use

Installation Notes

Installing the BMW M5 F90 carbon hood is a direct replacement of the factory part. Professional installation is recommended:

1. Open the hood and remove the OEM engine bay insulation (to be transferred to the new hood).
2. Detach the gas struts and remove the hinge bolts.
3. Because the carbon hood is noticeably lighter than steel, the OEM gas struts may overshoot or change the closing feel; a lower-newton gas strut upgrade is recommended.
4. Mount the carbon hood to the hinges and test-fit for alignment (4-6 mm gap to fenders).
5. Adjust the latch mechanism; transfer the engine insulation material.

Care & Maintenance

Wash with pH-neutral car shampoo. Apply carbon-safe sealant every 6 months. Keep pressure washer nozzle at least 30 cm from surface. Water entering the vents is normal: the design includes drainage.

FAQ

Does this hood fit the F90 LCI (2021+)?
No. The F90 LCI facelift has different hood sheet geometry. M5 F90 LCI owners should contact BYC for hood availability.

Compatible with both standard M5 and M5 Competition?
Yes. This hood fits both 2018-2020 standard M5 F90 (600 hp) and 2019-2020 M5 Competition F90 (617 hp): the hood geometry is identical across pre-LCI F90 trims.

Is this the same as the BMW M5 F10?
No. M5 F10 (2011-2017) is the previous generation with completely different body panels.

Does it fit BMW M3 F80 / M4 F82?
No. M3 F80 and M4 F82 have different chassis and hood geometry.

Will I need to change the gas struts?
Recommended. Because the carbon hood is significantly lighter than steel, the OEM gas struts may push the hood too far up or change closing feel. Lower-newton replacement struts are widely available.

Are the vents actually functional?
Yes. The vents are designed to evacuate hot air from the engine bay and help reduce S63 V8 temperatures under driving conditions.

Will rain damage dry carbon parts?
No. Autoclave-cured prepreg carbon is fully waterproof and weather-resistant.

Shipping time?
In-stock items ship within 1-3 business days via partner couriers. International shipping available. Parts sourced to order are delivered within 30 days of the order date at the latest.

Warranty?
Manufacturing defects are covered by a 24-month BYC warranty, in addition to your legal rights.
