Why choose a BMC air filter?

1. Better air flow to the engine:

The cotton gauze BMC uses has larger links, allowing a better air flow, but using several layers of oil soaked cotton allows to block any impurity larger than 7 microns.

2. Greater retention and screening:

BMC air filters scored an impressive 97.5% filtration efficiency at ISO5011 test.

3. Wider filtering area:

Maximum air permeability and higher air flow passage.

4. The choice of champions:

BMC equips some of the most important teams in Formula 1, MotoGP, WorldSBK.

General information

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 more efficient filtration, guaranteeing the 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 made 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 oxidation due to air humidity.

All BMC air filters are pre-oiled, and they can be washed and regenerated using the appropriate BMC regeneration kit.
