The 2010+ MV Agusta F4 HE (High Efficiency) air filter is unlike any other air filter on the market. With the MWR HE and Race air filters all inlets will get the same quantity of air regardless the speed of the motorcycle, wind direction or turbulence from the fairing. Incoming turbulent air is stabilized and accelerated around the edge of the air splitter plate before passing through the filter into the airbox. The net result is a greater volume of air evenly distributed through the airbox increasing power and simplifying tuning since all inlets are getting the same quantity of air.
Please note that to install this filter you must modify your airbox. You must unbolt the tube from the top of the airbox lid and cut the steel gauze from the filter instillation frame with a razor blade. Both are very simple procedures. We can send images of the process if needed.
MWR Air Filters are handmade in the Netherlands of top quality materials. Unlike all other foam filters MWR Air Filters are made entirely from special Fire Resistant (FR) foam and use FR biodegradable filter oil, protecting both the environment and your engine.
All MWR Air Filters are shipped out pre-oiled and ready to install. Filters should be cleaned and re-oiled with MWR filter cleaner and oil once a year to ensure best performance and the longest filter life. Filters can be washed and oiled up to 25 times.
