MMX Cotton panel air filter | BMW G8x | M2 | M3 | M4

Looking for a simple, warranty-friendly upgrade for your G-Series M-Car? One of the easiest ways to upgrade the breathing abilities of your S58-engined M2, M3 or M4 is with our pair of replacement performance panel air filters. Fitting is very straightforward and installed in around 10 minutes, and easily returned to standard, should you ever wish. Not to mention, completely washable and reusable.

By removing the inevitable restrictions that the standard paper panel filters give, our panel filters allow a 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. Meanwhile, OEM-standards of design, quality, materials and construction means it fits like a factory part, lasts like a factory part. Sold as a pair. Put simply, we're confident that these are the best panel air filters you can buy.
