Looking for a simple, warranty-friendly upgrade for your car? One of the easiest and best ways to upgrade the breathing abilities of your S55/S63 FX M-car is with these replacement performance Panel Air Filters.

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 filters give, our Panel Filters allow a small but very 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 believe these are the best Panel Air Filters you can buy.
