Karbonius E36 M3 (Euro S50) Carbon Airbox
The Karbonius E36 M3 (Euro S50) Carbon Airbox is an Evo-style carbon intake solution designed specifically for the European S50B30 and S50B32 engines. Engineered for improved airflow, this airbox — when combined with an Alpha-N remap — has been validated by Karbonius to deliver a power gain of approximately 30 horsepower alongside improved throttle response and an exceptional induction sound.
Manufactured from 100% prepreg carbon fiber and autoclave-cured at Karbonius' facility in Spain under ISO 9001 Management Quality System standards, the airbox weighs just 1.9 kg and is finished in a UV-protective clear coat, available in gloss or matte over a 2x2 twill or 1x1 plain weave. CNC-machined aluminum components and stainless-steel hardware complete the kit. Each piece is individually numbered to guarantee origin and authenticity.
