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. BMC air filter is produced using a "Full Moulding" system that enables the characteristic red filter to be realized from a single mold 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. The BMC Air Filter is a multi-layered cotton gauze soaked with low-viscosity oil that is covered in an epoxy-coated alloy mesh to ensure protection from petrol fumes and oxidization due to air humidity. This panel / cylindrical air filter is commonly called a "replacement air filter." It is installed in the vehicle's original airbox to replace the OEM air filter. For those who want to add more power and optimize airflow while protecting the engine, they are very effective in achieving this goal. Thanks to the low-pressure drop and high filtration efficiency, these filters allow better performance at the medium-high rpm range. These BMC Air Filters are made by hand in Italy. They are constructed from the highest quality materials and designed for a long life. This filter is designed to provide maximum protection for your engine whilst improving performance and increasing fuel economy.
