Alongside standard filters, BMC has produced a race version for the most important bike models. These filters have the same shape as the standard version but with a different filtering body designed to take in more air than other air intake systems, but without compromising its filtering properties. BMC RACE filters are for people who are not satisfied with the standard performance of the bike and want to improve the engine by upgrading other bike parts. With this filter they can find the best balance for a bike aiming for the top. BMC RACE filters are identified by an orange line inside the filtering body. BMC air filters are 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.
