bmc Air Filter The know-how acquired on the circuits is introduced directly into the production of the series filter, for the most demanding motorcyclists a product to offer, which is being tested, Potenza brings and is constantly evolving. The materials used are the best currently available on the market. The filters are made in a single rubber frame to avoid possible breakage. The filter element is made of a special cotton fabric (4 layers), soaked in a low adhesion oil. It is surrounded by an aluminum mesh that is treated with an epoxy resin, order against gasoline vapors and oxidation to resist. In addition, cotton has the advantage of being washable and reusable. With these characteristics, the bmc air filter (Air Filter) guarantees a higher air flow rate than the traditional paper filters used original, a minimum loss of pressure of the incoming air and therefore lead to improved engine performance. - Durability: Washable and reusable, no replacement needed - Wider filter surface - Maximum air permeability (4 layers of cotton) - Greater absorption and filtration - Better pressure drop ratio - Tested by international methods
