BMC FB01073 - 2019+ BMW 5 (G30/G31/F90) M 550 IX Replacement Panel Air Filter

The cotton sports air filter is installed in the airbox to replace the original air filter. It is produced with high-performance materials that allow an increase in the air flow to the engine compared to the original paper or sponge air filter, while ensuring superior filtration efficiency: thanks to the combination of the different oiled layers, the containment of all impurities are guaranteed down to a minimum of 7 microns (international standard certified for ISO5011 filtration), while OEM paper filters typically require total filtration of particles down to a minimum of 10 microns.

The test is performed in the airbox, therefore with the flow restrictions depending on the standard air inlet.

BMC cotton sports air filters are made with a process called "Full Molding" which allows you to obtain the characteristic red filter from a single mold without requiring gluing in the corners, which can easily break. The particular rubber used in BMC filtration systems is practically non-deformable over time and has excellent adhesion characteristics to any form of airbox.

BMC air filters consist of a multi-layered cotton fabric soaked in low viscosity oil, sandwiched between two aluminum cross-linked structures. The aluminum nets are treated with epoxy resin to protect them from oxidation caused by fuel vapors and humidity in the air.

All BMC air filters are washable and regenerable using the special washing kit, allowing you to save on periodic filter replacement.
