WSBK Full Race Air Filter Suzuki GSX-R 1000/GSX-S/F/Z/Katana

Very exclusive, custom made air filter, only for track bikes.
The shape of the filter is adapted to the airbox and made as big as possible which increases the filter surface enormously. 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, deliberately placed to create as equal an airflow as possible across all cylinders. The filters are hand cut and hand made.
For perfect performance, throttle response and durability,  ECU remapping recommended.
