Dry Carbon Engine Hood - Motorsport for E46-M3

I built a prototype dry-carbon engine hood for the E46-M3.
It weighs 4.7 kg, and the integrated frame ensures sufficient strength. The center duct is positioned to expel hot air that has passed through the radiator, while the side grilles vent hot air from the engine compartment to aid cooling.
The duct shape, which protrudes from the surface of the engine hood, creates a flow of air to enhance the exhaust efficiency.
