Product description

The Karbonius E36 Airbox intake with integrated snorkel for S50B30 and S50B32 engines is a high-performance solution designed for the BMW M3 E36 and Z3M, combining maximum airflow, weight reduction, and motorsport sound.

Manufactured entirely from prepreg carbon fiber and autoclave-cured at our facilities in A Coruña (Spain), this airbox stands out for its exclusivity, precision, and premium finish. Weighing only 1.9 kg, it is one of the lightest and most advanced options on the market.

Its exclusive EV Style design with an integrated snorkel optimizes air intake, improving engine efficiency. Combined with Alpha-N tuning (not included), it allows for power gains of up to 30 hp, along with more direct throttle response and a spectacular sound.
