Dry carbon engine hood Motorsport for E46-M3

We have made a dry carbon engine hood prototype for E46-M3.
It weighs 4.7KG and has a frame to ensure sufficient strength. The center duct is arranged to exhaust hot air that has passed through the radiator, and the side grilles exhaust hot air from the engine compartment for cooling.
The duct shape raised from the surface of the engine hood generates an overflow and improves the exhaust effect.
