BMW M135i (F20,F21) N55, M2 (F87) BMC High Flow Filter | FB740/20

Description The BMC high-flow filter for your BMW N55 (F20, F21) is designed to permit very high flow rates, minimise restrictions, maximize filtration and provide a long-life filter. It uses proprietary woven cotton and metal mesh with a precision moulded rubber base. It is designed as a filter replacement and drops directly into your OEM airbox. This BMC High Flow Filter (HFF) is made of highly performing-materials that allow an increased air flow combined with a more efficient filtration, guaranteeing containment of all impurities from as small as 7 microns (compared to OEM’s 10 microns). BMC filters are made of a multi-layered cotton gauze soaked with low-viscosity oil covered with an epoxy-coated alloy mesh to ensure protection from petrol fumes and oxidization due to air humidity. All BMC air filters are pre-oiled, and they can be washed and regenerated by using the appropriate BMC regeneration kit.
