BMW M5 E39 (1998-2003) Prepreg Dry Carbon Fiber Vented Hood

Engineered for BMW M5 E39 (1998-2003) owners, this Prepreg Dry Carbon Fiber Vented Hood delivers engine-bay heat extraction and lightweight performance to the iconic V8 super-sedan. Manufactured in Europe and quality-controlled by BYC Performance, this hood bolts directly to OEM mounting points.

The M5 E39 is powered by the S62B50 4.9L V8 naturally-aspirated engine producing 400 hp. This vented carbon hood is noticeably lighter than the OEM steel hood — vent geometry is milder and more daily-driver friendly than the GTR variant.

Key Features

• Classic Vent Channels: Mild, daily-friendly vent geometry — extracts engine-bay heat.
• Prepreg Dry Carbon: Autoclave-cured under high heat and pressure, a more consistent weave.
• Lightweight: Noticeably lighter than the OEM steel hood.
• 2x2 Twill Weave: High-gloss UV-protective clear coat.
• Direct OEM Fit: Plug & play on M5 E39 (1998-2003) hinge and latch points.
• Thermal Benefit: Vent channels reduce engine-bay temperatures at speed.
• Pre-LCI and LCI Fitment: All E39 M5 1998-2003.

Prepreg vs. Wet Carbon

• Autoclave-cured → a more consistent weave
• A controlled resin ratio → very high strength for its weight
• The production method widely chosen in motorsport

Vehicle Fitment

• BMW M5 E39 Sedan LCI (2000-2003) — S62B50 V8 NA 400 hp
