Karbonius E46 M3 Carbon Cabin Filter Cover
The Karbonius E46 Carbon Cabin Filter Cover is a precision carbon fiber reproduction of the factory plastic microfilter cover (OEM part number 64318363423), bringing a premium carbon aesthetic to one of the most accessible interior upgrade points on the E46 platform. At just 150 grams, this high-quality piece retains the OEM twist-lock mounting hardware for a factory-style installation that takes only minutes.
Manufactured from 100% prepreg carbon fiber and cured in mold and autoclave at Karbonius' facility in Spain, the cover delivers the finest finish available in its class, with superior thermal and structural stability over the original plastic unit. The UV-protective varnish finish, available in gloss or matte, accentuates the carbon fiber weave and provides long-term durability.
Each piece is individually numbered to guarantee authenticity and origin — a hallmark of Karbonius composites.
