MMX Performance Cotton Panel Air Filter | F8X S55 / F1X S63

The MMX Performance Cotton Panel Air Filter is one of the easiest power-boosting upgrades you can make to an S55- or S63-powered BMW. The kit drops directly into the OE airbox in roughly 10 minutes (no airbox modification, no cutting, no fuss) and is fully washable and reusable, so it's a one-time purchase that stays with the car.

Each filter is built from MMX-developed cotton gauze media that removes the inevitable airflow restrictions of a standard paper panel filter. The result is a worthwhile increase in airflow through to the turbos, which translates to crisper throttle response, a more aggressive induction note, and meaningful power gains across the rev range. OEM-standards of design, quality, materials and construction mean the filter fits like a factory part and lasts like a factory part.

The kit is sold as a pair, which matters: S63-powered M5 and M6 cars use both filters at once (one per airbox, twin-airbox setup), while S55-powered M2 Competition / CS, M3, and M4 cars use a single filter, so the pair covers the current service and the next.

Easily returned to standard if you ever wish, and arguably the best panel air filter you can buy for these engines.
