BMC Replacement Air Filter for Ford Focus ST (MK2)
BMC air filters are designed and produced to ensure a higher air flow than original paper filters. In F1, for example, BMC cotton filters minimize the loss of air flow pressure passing through the air filter; this way ensures the best conditions for full exploitation of maximum power. Therefore the benefits of replacing the original paper filter with BMC cotton air filter, produced using the same technology and materials as the F1 air filters, are evident.
Design and Materials
Qualified engineers using advanced software and expert technicians using the latest technologies produce BMC air filters. An F1 filter must be very light, must be made of the best raw materials and must improve performance. For this reason, we use only alloy mesh with epoxy coating to ensure protection from petrol fumes and from oxidization due to the humidity of the air. The filtering material is composed of a special cotton gauze soaked with low-viscosity oil to give you the best air permeability.
BMC technical staff has developed a particular production system based on soft rubber moulding which produces the familiar BMC red filters. They are made in one single piece with no welded joints in the corners, thus avoiding breaking risks. This system, called "Full Moulding" comes from R&D in F1 and it is significant of BMC air filters' technical and quality specifics.
The panel / cylindrical air filter is commonly referred to as "replacement air filter". It is installed in the vehicle's original airbox to replace the OEM air filter. It 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 air filters are produced using a "Full Moulding" system that enables the characteristic red filter to be realized from a single mould with no welded joints thus avoiding easy breakage. The rubber used in BMC air filtering systems has a long life, is very durable and has optimum adhesion characteristics to all shapes of airboxes.
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.
