BMW M3 G80 / M4 G82 | Prepreg Dry Carbon Fiber Front Air Duct

BMW M3 G80 / M4 G82 Prepreg Dry Carbon Fiber Front Air Duct

Engineered for BMW M3 G80 and M4 G82 owners who want a part that's both functional and visually aggressive, this Prepreg Dry Carbon Fiber Front Air Duct (brake cooling duct) channels air from the front bumper directly to the front brake rotors. On track it helps lower brake temperatures and reduces fade risk while delivering aggressive M Motorsport character at the front. Autoclave-cured by leading manufacturers around the world and quality-controlled by BYC Performance, this BMW G80 / G82 carbon air duct set fits OEM front bumper cutouts and clip points directly.

If your BMW M3 G80 tuning or M4 G82 modification build includes track days, the dry carbon front air duct set is a functional upgrade for the S58-powered current-gen M3/M4 family (473-543 hp). The same set fits the M3 G80 Sedan, M4 G82 Coupé and M4 G83 Convertible.

Key Features

• Prepreg Dry Carbon Technology: Cured under high heat and pressure in an autoclave for a more consistent weave.
• Functional Brake Cooling: Channels air from the front bumper directly to the front rotors; helps lower track brake temperatures.
• Motorsport Aesthetic: Open air-intake channels deliver real race character.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under a UV-protective high-gloss clear coat.
• OEM Fit: Direct fit to factory G80 Sedan and G82/G83 Coupé/Convertible front bumper cutouts and clip points.
• Pair Set: Symmetric left and right air ducts ship together.
• UV & Chemical Protection: Clear coat resists fading and road chemicals.

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 → very high strength for its weight
• The production method widely chosen in motorsport
• Minimal UV fading over years of use

Installation Notes

Installing the BMW G80 / G82 carbon front air ducts:

1. Detach the OEM plastic mesh/cover from the side openings of the front bumper.
2. Test-fit the new carbon air duct for alignment.
3. Seat the duct into the factory clip points with gentle pressure.
4. If needed, secure with the supplied hardware from below (to the manufacturer's recommended torque).
5. Visually verify that airflow is being directed toward the brake rotor.

Care & Maintenance

Wash with pH-neutral car shampoo. Periodically clean road dust from the inner duct channels. Apply carbon-safe sealant every 6 months.
