Karbonius E9X M3 Carbon Front Intake Ducts

The Karbonius E9X M3 Carbon Front Intake Ducts are precision replacements for the OEM plastic air ducts on the S65-powered E9X M3, completing the Karbonius intake system and delivering a clean, full-carbon engine bay appearance. The set weighs just 450 grams — significantly less than the OEM plastic counterparts — and is manufactured with the same prepreg carbon fiber and autoclave process used across all Karbonius intake components.

Karbonius components are produced through a combination of expert hand-crafting, premium raw materials, and modern manufacturing technology. With over 15 years of carbon fiber production experience, Karbonius' team meticulously inspects every piece before it leaves the facility in Spain, ensuring dimensional accuracy and a consistent, high-quality finish.

Each duct set is direct replacement for OEM references 13717838285 (front duct) and 13717541738 (rear duct), and is individually numbered to guarantee authenticity.
