Looking for a simple, warranty-friendly upgrade for your car? One of the easiest and best ways to upgrade the breathing abilities of the F2x & F3x B58-powered M140i, M240i, 340i, 440i or the B48 2.0 4 cylinder cars is with a replacement performance panel air filter.

Allow your engine to breathe better and operate more efficiently – and so improve the engine’s airflow, and power and fuel economy gains will follow.

By removing the inevitable restrictions that the standard paper panel filter gives, our Panel Filter allows a small but worthwhile increase in airflow through to the turbo.

We've developed our own range of MMR performance cotton gauze filters that easily drop into the OE airbox which provide excellent filtration properties, combined with instant performance increases and induction noise enhancements.

Our tests have shown that it can deliver an additional 15NM of torque on a standard B58 engine. A small but worthwhile difference.

Meanwhile, OEM-standards of design, quality, materials and construction means it fits like a factory part; lasts like a factory part.

Put simply, we believe it’s the best Panel Air Filter you can buy.

Please note, not for the newer G-Series cars with these engines, which require filter part number MMR01-1701.
