BMC WASHABLE AIR FILTER YAMAHA FM387/04

Why choose a BMC air filter?

The choice of champions:

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

1. Better airflow to the engine:

The cotton gauze used by BMC has larger links, allowing for better airflow, but the use of multiple layers of oil-soaked cotton allows for any impurities larger than 7 microns to be blocked.

2. Greater retention and detection:

BMC air filters achieved an impressive 97.5% filtration efficiency in the ISO5011 test.

3. Larger filtering area:

Maximum air permeability and greater airflow passage.

4. The choice of champions:

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

General information

The cylindrical/panel air filter is commonly referred to as a replacement air filter. It is installed in the vehicle's original air box to replace the OEM air filter. It is made from high-performance materials that allow for increased airflow combined with more efficient filtration, ensuring that all impurities are contained from as little as 7 microns (compared to 10 microns for OEMs).

BMC air filters are manufactured using a Full Molding system that allows the characteristic red filter to be made from a single mold without welded joints, thus avoiding easy breakage. The rubber used in BMC air filter systems has a long life, is very durable and has optimal adhesion characteristics to all shapes of airboxes.

BMC filters are made from a multi-layer cotton gauze soaked with low viscosity oil covered with an epoxy coated alloy mesh to ensure protection against petrol vapours and oxidation due to air humidity.

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