MWR Perfomance & Racing Air Filter for the Aprilia RS 457

The foam material of our racing filters have a much more open structure, which makes the protection of a much shorter duration, note: protection is 100% but much shorter, the maintenance frequency is so high that these filters are NOT suitable for roadbikes Our roadbike filters have a maintenance frequency of once a year, regardless of the mileage. Stick to this so that the foam cannot dry out and the protection for the next year is 100% insured. In countries around the Equator with extremely high temperatures and extremely high humidity, road engine filters must be serviced at least twice a year. Racebike filters can handle the same maintenance frequency as normal. Only MWR Airfilter oil may be used because this oil is biodegradable and therefore also resistant to backfire So …. very simple, the red filters are for the road bikes and black filters are for the track & race bikes Below you can read again the differences between all our filters as described on our website
The difference between the different type of MWR Airfilters in details

1) The Performance airfilter , excellent performance and max. protection . No copy of the std. filter , always searching for solutions , either it’s the performance , protection or fitment . Caution: clean and re-oil at least once a year with MWR airfilter oil & cleaner . In countries around the Equator with extremely high temperatures and extremely high humidity, road engine filters must be serviced at least twice a year. Remapping the ECU or the Fuel Control Module is recommended.

2) The Full Race airfilter , developed With the corporation of KHI , BMW , MV Agusta and MotoGP teams we developed a new style , very exclusive customized airfilter for track and racebikes , NOT for roadbikes , which increases the filtersurface enormously . The shape of the filter is "adapted" to the airbox to make it as big as possible , one of the reasons why we can't make the WSBK filter for every bike . We are able to increase the filtersurface from 50 - 100% , depending on the type of bike. More & bigger surface means less restriction , a better protection and the performance increase is in this case enormously. All WSBK filters are hand cut and hand glued. These new style WSBK filters are build with two different kind of foam materials . One part is foam material used for our roadbikes , the rest is the foam material for the full racefilters . The road material is placed on a conscious place to create the same effect as the splitter plate on our “HE” & “R” filters. Remapping the ECU or installation of a fuel module is necessary For the fueling you need to approach the same way as with our "HE" & "R" filters . This means tune each cylinder separate and secondairy injectors seperate from the main injectors.Caution : The Full Race airfilter protects for 100% but for a short period of time , check afther each raceweekend your filter , use only MWR filter oil & cleaner . Make sure you start each raceweekend with a well oiled filter.

Top teams and riders in MotoGP, Moto2, WSBK, WSS, BSB, MOTO AMERICA, and other championships choose MWR Air Filters for a reason!

And yes, the oil and filter materials are naturally non-flammable.
