Give your BMW’s turbocharged motor the airflow it deserves with this MMR high‑flow drop‑in intake element for B58 and B48 applications. Swap it straight into the factory air box for a noticeable improvement in throttle response, a deeper induction tone and freer breathing without the cost or fuss of a full induction kit. Perfect for daily driving, track days and tuned cars alike.

Built from premium multi‑layer cotton gauze with a precision rubber surround, this reusable, cleanable insert is engineered to optimise intake efficiency while maintaining excellent dust trapping. Our workshop has fitted plenty of these on customer cars and on our own builds. Feedback is consistently positive about the sharper pick‑up and the more purposeful turbo spool sounds.
