BMW M5 F90 LCI Prepreg Dry Carbon Fiber Front Air Duct

Engineered for BMW M5 F90 LCI owners, this Prepreg Dry Carbon Fiber Front Air Duct transforms the front fascia with aggressive M Performance styling while optimizing brake and engine cooling. Manufactured in Europe and quality-controlled by BYC Performance, this BMW M5 F90 LCI carbon front air duct bolts directly to OEM mounting points — no cutting, drilling, or modification required.

If you're building a serious BMW M5 F90 LCI tuning project and need a part that exceeds the factory plastic duct in both performance and finish, this dry carbon front air duct is built for you. Autoclave-cured prepreg carbon fiber is noticeably lighter than wet-lay carbon parts, with strong structural integrity and outstanding long-term UV resistance. Engineered to match the aggressive character of the S63-powered F90 LCI M5 — 600 hp standard, 617 hp Competition, and 635 hp CS — this duct 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 more consistent resin distribution and a more consistent weave.
• M Performance Styling: Carbon version of the OEM F90 LCI M5 front bumper duct design. Noticeably lighter than the factory plastic part.
• Enhanced Cooling: Optimized duct geometry channels airflow to brake and radiator zones, reducing heat soak.
• 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 LCI M5 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

FAQ

Does this fit the F90 pre-LCI (2018-2020)?
No. The pre-LCI M5 F90 has different bumper geometry; pre-LCI owners should contact BYC for air-duct availability.

Compatible with standard M5 LCI, M5 Competition LCI, and M5 CS?
Yes. This duct fits 2021-2023 standard M5 F90 LCI, M5 Competition F90 LCI, and the limited 2022 M5 CS — the LCI front bumper geometry is identical across these 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 bumper geometry.

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