Product description

The Karbonius Vented Hood for BMW M3 E46 combines significant weight reduction with improved functional thermal management of the engine bay, while maintaining an aesthetic perfectly integrated with the vehicle’s original lines.

Made entirely from pre-impregnated carbon fibre (prepreg) and autoclave-cured, this bonnet has been developed and produced at our facilities in A Coruña (Spain) by highly qualified staff with extensive experience manufacturing carbon automotive components.

This is a reinterpretation of the original M3 E46 hood, incorporating ventilation inlets carefully integrated into the design. These allow hot air accumulated in the engine bay to be evacuated, promoting better cooling and more efficient thermal management during sporty driving or under demanding conditions.

The hood’s inner structure has also been redesigned, adapting the structural reinforcements to the new exterior design. The part is manufactured in two sections (inner and outer) which are then bonded with high-strength structural adhesives, resulting in a lightweight and extremely rigid assembly.

Compatible with original BMW components, it allows reuse of OEM latches, kidney grilles and grilles, making integration into the vehicle easier.

For those looking for different finish levels, the bonnet is available in several versions:

EXTERIOR:

  • Supplied straight from the mould. No clear coat inside or out. Ideal for custom projects or specific finishes.
  • Primed – ready to paint
  • 2×2 gloss exposed carbon, with automotive clear coat with UV protection for increased durability

INTERIOR:

  • Supplied straight from the mould. No clear coat inside or out. Ideal for custom projects or specific finishes.
  • 2×2 matte
  • 2×2 gloss
  • Forged carbon
