Then you do not want be buying a rig from me or ANYONE who hits the trail with me (Including all of the folks that have participated in the Alaska Cruiser Trek since 2001... Door handle deep in water is pretty routine.To me a snorkel looks dumb on any vehicle unless it is up to it's door handles in water.
I wouldn't give much for a vehicle with a snorkel because there is a good chance that it has been up to it's door handles in water.
Years back my buddy dropped his 40 into a deep hole that surprised him and he hydro-destroyed his new engine, while it is adviseable to check every water hole when you are wheeling, stuff happens. I like a snorkle. If you havent waterproofed your dizzy big deal, you can dry it out but its hard to dry a rod out the side of your block.
Screw all the other reasons, I want a snorkel just so I can attend an Alaska Cruiser Trek...Then you do not want be buying a rig from me or ANYONE who hits the trail with me (Including all of the folks that have participated in the Alaska Cruiser Trek since 2001...

The cyclonic filter assembly in the '80s catches a bit of dust/dirt/debris over time. Even in road rigs. It is surprising how much that sump will have in it when the owners do not know it is there and never clean it. I would expect that one of the Donaldson cyclonic prefilter (or anything similar) would do an even better job. But I don't see much difference in the normal straight airflow snorklels that 99% of the US rigs use.Screw all the other reasons, I want a snorkel just so I can attend an Alaska Cruiser Trek...
That being said, in the Middle East snorkels made a big difference in keeping the filter clean.
I do believe @wngrog has a photo somewhere around here comparing air filters with/without snorkels.
As far as crossing water yeah a snorkel is great. One thing to remember if you need a snorkel in water is to ask yourself if you have taken the same effort to protect your diff breathers, transmission and transfer case breathers, ignition system, electrical wiring and exhaust with the same effort you put into getting air into the engine with the snorkel. I bet very few people have ever thought about that issue of water crossings.
As far as dirt and dust they are much more useful there than anyone wants to admit. Having run farm machinery and military vehicles in dirt/dust ( and some fording) the snorkel removes the air source from under the hood to above the roof line where much cleaner air can be found to draw from. If you are operating in that environment the snorkel is very VERY useful and can greatly extend your PM intervals.
Please note I said extended, it won't keep it clean like you use it as a commuter car but it will make the time between cleanings or filter replacement longer.
