MWR WSBK Air Filter 2014- BMW S1000R , 2009-2019 S1000RR

The shape of the WSBK filter is adapted to the airbox to give it the largest surface area possible. A larger surface means less restriction and better protection and performance increase. All WSBK filters are assembled by hand and are built with two different kind of foam material . One part is the foam material used for roadbikes, the other is the material used for the full race filters. The materials are arranged to create the same effect as a splitter plate to evenly distribute the volume of air into the intake. Remapping the ECU or installation of a fuel module is necessary with these filters.
