Improve your BMW's airflow, and power gains will follow.
By removing the inevitable restrictions that the standard paper panel filter gives, our panel filter allows 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.

Put simply, we're confident that this is the best panel air filter you can buy.
