VW GOLF IV 1.9 TDI, BMC Sports Air Filter

The BMC air filter is composed of two layers of aluminum mesh with an epoxy coating to protect the mesh structure, which holds the oiled cotton filter material, arranged in multiple layers. This ensures a high level of filtering efficiency and minimal pressure drop, or the difference between the air to be filtered and the air filtered. The oil used helps retain impurities in the air, allowing for continuous filtration. The cotton filter element is co-molded inside an external support frame that fits directly into the airbox, ensuring perfect installation. Every stage of the production process (from design to production) is carried out in Italy by Italian technicians using the finest materials.
