I took my bike out on fresh oil and this amazing BMC Air Filter it felt like a new bike. This is the only filter i will ever put in any bike I own or work on. The filters come pre-molded so you just pull out the old one and pop the new one in
Alongside their standard air filters, BMC developed a Race version for the bike models most likely to spend their time on the track. These filters have the same shape as the standard version, but utilize a different filtering body designed to take in more air than stock or standard BMC Air Filter-equipped intake systems, and they do so without compromising its filtering properties. BMC Race filters are for riders who are not satisfied with the standard performance of their bike and want to improve the engine by upgrading it extensively. With this filter installed, they can find the best balance for a bike aiming for the very top. BMC Race filters are easily identified by an orange line inside the filtering body.
