sfvickery,
I have the OEM high rise intake/air filter on my 2011 900xt and yes the filter is a high capacity filter that is different from the fro the original filter. Now I don't know if the original filter will appropriately fit the high rise. I've had mine since 2011 and have not replaced the filter, in fact since changing to the high rise, I've only cleaned the filter twice. The original filter due to it's location required cleaning every other week due dry dusty periods.
