Question about this product?

We're happy to help.

The MMX Performance F8X (S55) / F1X (S63) Elite Series Panel Air Filter Set is the top-tier filtration upgrade for both the S55 and S63 BMW M-cars. Where the standard MMX cotton gauze filter is the entry-point upgrade, the Elite Series steps up to a premium tri-foam construction inspired by Formula 1, World Rally, and Touring Car filtration technology, engineered for both road and competition use.

Each filter uses a layered tri-foam media built around a structural cage, designed to maximize airflow with minimum pressure drop. The result is a filter that delivers significantly more airflow than the standard paper element while still providing outstanding filtration efficiency. Throttle response sharpens, the induction note becomes more present under load, and the turbos see cleaner, more abundant air.

The set drops directly into the OE airbox in roughly 10 minutes, with no airbox modification or cutting. Crafted to OEM standards for design and durability, the filter is washable and reusable with the appropriate cleaning kit, making it a one-time purchase that stays with the car.
