BMC 2019+ BMW X3 M (G01/F97) / 2019+ BMW X4 M (G02/F98) Replacement Panel Air Filters

The BMC Air Filter FB01090 is a high-flow, panel air filter kit designed as a direct drop-in replacement for the OEM airbox in specific BMW X3 M (F97) and X4 M (F98) models, including Competition versions. It features BMC’s one-piece Full-Moulding red rubber frame and multi-layer oiled cotton gauze, reinforced by an epoxy-coated alloy mesh. This design improves intake efficiency while filtering particles down to approximately 7 microns, which is tighter than typical OEM paper filters (around 10 µm). The filter is washable and reusable, and it's designed for a perfect OEM-style seal in the factory airboxes. The FB01090 is supplied as a four-element kit for the dual-airbox S58 setup.
