___________________________________________________
The MWR Full Race Airfilter is developed on track , developed for racebikes NOT for roadbikes , not on dynometer but in real life , on track , professional racebikes with dataloggers . protection is on the same level as the performance filter & “HE” filter only for a shorter time due to the much more open structure of the foam materials.
Unlike all other sportsfilters the racefilter creates a much better , equal airflow over all cylinders , means you need to adapt fueling of all cylinders seperatly to achieve maximum effect of the “HE” filter . Concerns all twins , V-twins , three , four , and V4 engines
Remapping the ECU or Fuel Control Module is highly recommended .
 
The difference between our roadbike and racebike filters
The foam material of our racingfilters have a much more open structure compared to the roadfilters foam material which makes the duration of the maintainance much shorter , the protection is at the same level as our roadbike filters but for a shorter time , therefore the maintainance is much more intensive. Maintainance frequency for racebike filters are afther every two raceweekends. Therefore are racebike filters are NOT suiteable for roadbikes
Our roadbike filters have a recommended maintainance frecuency of once a year …. regardless the milage .
Even when you have ridden 50 miles that year stick to the guidelines , priority for the filter is that the foam must not dry out , keep it “wet” from oil
In countries around the Equator with high tempature and high humidity , the frequence must shortend to twice a year . Racebike filter can stay with the normal frequency of maintainance
Only MWR Biodegradable filteroil and Biodegradable filters cleaner may be used to protect the filter also from backfire.
