BMW M3 G80 / M4 G82 Prepreg Dry Carbon Fiber Front Fender Vent

Engineered for BMW M3 G80 and M4 G82 owners, this Prepreg Dry Carbon Fiber Front Fender Vent drops into the OEM fender vent opening to bring track-inspired side-profile detail and help extract hot air from the wheel well. Manufactured in Europe to factory-spec tolerances and quality-controlled by BYC Performance, this BMW G80 / G82 carbon fender vent matches the OEM opening geometry exactly.

If you're building a serious BMW M3 G80 tuning or M4 G82 modification project and want a detailed carbon accent that completes the side profile, this dry carbon front fender vent is built for you. Autoclave-cured prepreg carbon is stronger and more UV-resistant than the OEM plastic vent cap. Fits all S58-powered current-generation cars — M3 G80 Sedan, M3 Touring G81, M4 G82 Coupé and M4 G83 Convertible (473-543 hp) — across every trim, including Competition, CS and CSL. Front fender geometry is identical across all G80/G82 variants.

• OEM-Style Upgrade: Mirrors the factory vent cap design with a carbon-weave finish.
• Race-Grade Strength: Very high strength for its weight.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under high-gloss UV-protective clear coat.
• Direct OEM Fit: Plug & play on M3 G80 Sedan and M4 G82/G83 Coupé/Convertible fender openings.
• Pair Set: Supplied as a left + right set.

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
