The Karbonius E46 M3 S54 Carbon Engine Cover - OEM Style replaces the factory plastic engine cover (OEM part number 11127838754) with a direct-fit carbon fiber reproduction that instantly elevates the appearance of any S54-powered engine bay. Weighing just 700 grams, the cover retains every OEM mounting point for a straightforward installation while delivering superior materials, finish, and thermal stability.
Manufactured from 100% prepreg carbon fiber and cured in molds in an autoclave at Karbonius' facility in Spain under ISO 9001 quality management standards, every cover is produced by qualified staff through a manual process. The high-gloss varnish finish accentuates the carbon fiber weave and provides UV protection for long-term durability.
Each piece is individually numbered to guarantee origin and authenticity — a hallmark of Karbonius composites.
