WSBK Full Race Air Filter Aprilia RSV4 RF/RR (2015-2024)

Very exclusive, custom-made air filter, only for circuit bicycles.
The shape of the filter has been adapted to the airbox and made as large as possible, which enormously increases the filter surface. One of the reasons why MWR can't make it for every type of motorcycle. Depending on the motorcycle, they have been able to increase the filter surface from 50 to 100%. A larger surface = less restriction = more power and better protection.

These new style “WSBK” filters are constructed from two different foam materials, placed in a conscious location to create as much equal airflow as possible across all cylinders. The filters are hand cut and hand made.
For perfect performance, throttle response and durability  ECU remapping recommended.
