MWR High Efficiency & Racing Air Filter for '09-'14 Aprilia RSV4

Our new and improved HE air filter can now be installed without the original filter holder. This new design creates a better seal with the airbox and increases the airflow between the filter frame and splitter-plate which equates to more power for your bike (average gains of the filter alone for most bikes, before any tuning or exhaust is 4-6 HP)!

The High Efficiency (HE) splitter-plate distributes the incoming air across all intake channels and the incoming turbulent air is stabilized and accelerated around the edge of the splitter-plate, which leaves you with a greater volume of air evenly distributed throughout the airbox for easier tuning and maximum power!

The full Race filters are developed on the track, NOT on a dyno, but in real life on bikes with Dataloggers being tested and developed in part with TOP Teams for the ultimate performance. With new materials and a new design, protection is on the same level as the filters above, only for a shorter time before they must serviced.
