In 14 years of wheeling in Colorado and Moab there was only 1 time a snorkel would have made any difference at all, even then it may have not helped because the water was halfway up the doors. 90% of the vehicles you see in the US with snorkels are for poser purposes only.
Did a few hours 2 ways on really dusty FSR last year, my stock intake on the XJ was more of a vacuum than an air cleaner. Having said that the filter did an excellent job of keeping the crud out...I cleaned it when I got home. It was in a word, clogged.
The new Cowl Snorkel so far seems to do an excellent job at keeping the dust out. Or at least to now more of the dust out. If it didn't your interior would be a dust bowl all the time...that low pressure air above the cowl works well to keep the dust away.
Still really digging the pre-filter idea. SOMEONE make one soon so I can copy it! lol
I'd beware of the spectre intake for dusty areas. I drove a friend's TJ with one a couple years ago. When I hit the highway and it had NO power I asked ******?! He told me the filter needed cleaned as it is so small it plugs up very quickly. Night and day difference after cleaning. Just throwing it out there as that would be deal breaker for me.

Where in the world did you see that? I jumped on mine for 200, almost ten years ago. Now they're $4-500 everywhere, including my search of ebay...
