I haven't verified this - The KTM PP filter (non-Aus model) has been withdrawn from sale. Just too many motors dusted out. If you have one of the 'POS' filters, lose it right now. I've seen one that was ruined by 3000 miles when the filter pulled away and dumped dirt. Needed the upper case/cylinders replaced along with valves. Owner was lucky, KTM warranty and KTM part, so it was all covered.
