This MWR open airbox airfilter will give the ultimate performance. The holding frame will be screwed in the airbox. Airfilter includes screwes & spacers. No modifications to the airbox needed , just remove the top-lid of the airbox .  Caution: Remapping the ECU or the Power Commander is necessary. Caution : cleaning and reoiling at least once a year regardless of the mileage. Because you open the airbox the inletnoise will increase....a lot.
