BMW F-series B48 and B58 performance cotton panel air filter - the fast, warranty-friendly upgrade for BMW 2.0 turbo B48 and 3.0 turbo B58 engines. Perfect for BMW F20 F21 F22 F23 F30 F31 F32 F33 platforms including M140i, M240i, 340i, 440i, 120i, 125i, 220i, 230i, 320i, 330i, 420i and 430i. This high flow, washable, reusable drop-in panel filter is a direct replacement for the OE paper element and is designed to improve airflow, throttle response and induction noise while retaining the factory airbox.
We have fitted and tested these MMR cotton gauze panel filters on our own cars and many customer cars, and they consistently deliver sharper response and a noticeable improvement in the way the engine breathes. On a standard B58 engine our testing has shown an additional 15 Nm of torque. Small change, big grin. Optimised airflow through the turbo inlet combined with excellent filtration means performance you can feel and protection you can trust.
