Product Description

The BMC FB819/04 is a direct-fit cylindrical performance filter built for the M133 turbocharged 2.0L four-cylinder found in the Mercedes-AMG A45, CLA45, and GLA45. It drops into the factory airbox in place of the stock element with no modification required, using the same oiled cotton gauze and Full Moulding construction technology BMC develops for its Formula 1 applications.

The cotton media retains filtration down to 7 microns while still delivering a meaningful airflow increase over the OEM paper filter, helping the M133 engine breathe more freely. Since the filter is washable and reusable rather than disposable, it's built to last the life of the vehicle with periodic cleaning and re-oiling - a straightforward upgrade for AMG 45-badged owners looking for a genuine airflow gain.
