In general, vehicles such as car or motorcycles require a total particle filtration efficiency up to a minimum size of 10 microns, to avoid any risk of passage of foreign objects that may damage the mechanical components downstream of the intake system (Air Flow Sensors, injectors, valves and segments). OEM air filters are made of paper and their main function is to protect the engine. These filters have high resistance to the air flow, which reduces the inlet pressure and reduces the engine's performance. BMC's air filters provide a considerably greater air flow. Furthermore, compared to a conventional paper filter, which at the time of maintenance must be replaced, the BMC air filter (being reusable) has a life equal to that of the vehicle itself. Another type of air filters on the market are synthetic filters, which BMC has produced for years only for non-road applications. The main difference between the BMC oiled cotton filters and filters made of synthetic material (for example plastic canvas) is the principle of impurities stoppage. The synthetics allow passage of particles in the size of the micro-filter material: it follows that a filter with 80 micron holes allows the passage of all items below that size, stopping only particles larger than the size of the hole (an example: the sand has a size of about 50 microns). The cotton has a larger plot, which favors the passage of a large flow of air and through the combination of different layers containing oil, ensure the stoppage of all the impurities from 7 microns up. To date, this concept is the best solution for both better filtration and higher performances.
Returns Policy
You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly.
