Mahle Air Filter   Clean intake air - one of the most important prerequisites for optimal engine performance, high torque, low fuel consumption, and the minimization of pollutant emissions.   With MAHLE air filters, dust, soot, and tire wear are filtered out by up to 99.9 percent. At the same time, an optimal air/fuel mixture is ensured. The high particle retention capacity guarantees long service intervals - even under extreme conditions such as heat, cold, or chemical influences.   Mahle quality filters prevent premature wear on valves, cylinder running surfaces, piston rings, plain bearings, and other engine components. To ensure consistently flawless filter performance, all filters should be replaced according to the intervals specified by the motorcycle manufacturers.

BMC Replacement Air Filter   The acquired know-how from the racetracks is directly incorporated into the production of the series filters, to provide the demanding motorcyclist with a product that is tested, delivers performance, and is in a constant state of evolution.   The materials used are the best currently available on the market. The filters are made from a single rubber frame to prevent any breakage. The filtering element is made from a special cotton fabric (4 layers), soaked in a low-tack oil.   It is encased in an aluminum mesh that is treated with an epoxy solution to be resistant to gasoline vapors and oxidation. Additionally, the cotton has the advantage of being washable and reusable.   Due to these features, the BMC sport air filters (replacement air filters) guarantee a higher airflow compared to the original paper filters, a minimal pressure loss of the incoming air, and thus lead to better engine performance.   - Durability: washable and reusable, no replacement needed - Wider filter surface - Maximum air permeability (4 layers of cotton) - Higher absorption and filtration - Better pressure drop ratio - Tested by international testing procedures
