I put the Airaid system with snorkel on my 2010 Rzr and every thing was fine until I added a rear window. The window causes the dust to swirl at rear and the snorkel sucked it all in. So if you have a rear window don't use the snorkel.
This is true with any snorkel system that draws from the bed area. In high dust conditions I would either remove the windows or add a paper pre-filter on top of the snorkel. Undo the clamp on the pre-filter, take it off, knock it against the tire a time or two and put it back on. Takes less than a minute and only requires a screw driver.
