As you all know The Guys at MWR are always on the hunt for power and to keep the Factory and Race teams happy. They have discovered that on the “big 1000cc bikes” the OE filter surface was too small. It doesn’t matter what filter you install, you always have a kind of restriction. The MWR “R” filter has been giving the best power overall compared with all other air filters. MWR and the MotoGP teams they developed a new style air filter that increases the filter surface enormously.More & bigger surface means less restriction and better protection. The secret in the new style filters is that they use two different kinds of foam materials. The part where the logo is printed is foam material used for our roadbikes, the rest is the foam material for the full race filters, placed to create the same effect as the splitter plate on the “HE” & “R” filters. Tests show average gains of 6.5HP over the MWR “R” filters.
**Caution: Remapping the ECU or the Power Commander is highly recommended.**
Only use MWR cleaner and air filter oil
