Product description

The Karbonius CSL Concept Engine Cover for BMW M3 E46 is inspired by the exclusive cover used by BMW on the M3 CSL Concept, reinterpreting its design with the highest carbon fiber manufacturing standards.

Entirely manufactured in preimpregnated carbon fiber (prepreg) and cured in mold and autoclave oven, this piece combines a minimalist and elegant design with ultralight construction and exceptional finish quality. All units are produced at our facilities in A Coruña (Spain) under ISO 9001 quality standards and by highly specialized personnel.

Its clean and exclusive design completely transforms the appearance of the S54 engine bay, offering aesthetics inspired by BMW Motorsport’s most iconic prototypes. The high-gloss finish with UV protection enhances the visible carbon weave and guarantees excellent durability over time.

The cover includes a custom stainless steel plate, available in M or CSL version, allowing the aesthetics to be adapted to the owner’s preferences.

Like all Karbonius parts, each unit is individually numbered and includes a certificate of authenticity, guaranteeing its origin and exclusivity.
