If you absolutely have to have a snorkel, I would want to be sure other components are able to tolerate full submersion in mucky water.

The computer (I'm not starting that argument, so I'll stick with the word computer...), hangs pretty low for one thing.
Can it and other stuff hold up to water submersion and potential corrosion after? The front diff, transfer case? All water tight?

Not telling you it is a crappy idea.
Just wanted to relay some things to consider if you go that route...

When I had my Jeep TJ, I heard stories of Jeep owners putting snorkels on. Mainly because they looked bad-ass driving around town. Then the horror stories of when they actually forded deep water and found out quick, that their snorkel system was not actually water tight. They sucked in water and had to deal with that mess.

If you get a snorkel. Whatever you get, you are going to want to make sure there is no doubt that it is 100% water tight, if you plan on fording water up to your hood. Even if it is plastered with RTV on every joint and pinhole, heat flexing and road vibration can make almost any attempt to seal out water fail. With air intake, even the smallest leak can be a huge problem quick.

One other thought... Better make sure door seals can hold back the flood waters too. Things like airbag modules and other electronic components GM placed on (or near) the floor probably don't like getting wet either.

I had a Jeep. I like adventure as much as anyone. But, If I were swimming through water deep enough to require a snorkel... I don't think it would be my stock Tahoe to do it in. I would probably look for something purpose-built for extreme off-road action with a not-legal-for road-use super high suspension lift and 35"+ tires.

Again, not dumping on your idea. Just want to make sure we don't see posts about how to deal with a hydro-locked engine or electronic issues later on.

Post pics of the project. We would all be interested in seeing what is done.

Those aftermarket snorkels look AWESOME. Adding one has crossed my mind before. However, I have some concerns.

1. Rain, is there a sump or something in the snorkel to keep rain out? I live in Southern Arizona where when it rains it rains like a waterfall. Even so maybe not quite enough to cause an issue? However, still concerns me.

2. You have vents on your differentials and transmission. You will trash the fluid going through water and need to change it more frequently. This is a problem with any intake, a bit unrelated.

3. Your engine won't run the same. It'll need some tuning. Kind of a minor detail.

4. The factory air intake is VERY carefully designed so as not to ingest rain, even to some degree going through water. I don't know exactly how deep it will tolerate. I think it pulls air from the fender / behind the head lights. Between leaky snorkels, and all their issues, I'd almost trust factory more than those snorkel contraptions. Although they do look damn cool.

If I was designing something I'd look to the military humvee design. It was designed by engineers with the whole system in mind and extensive testing to validate it works properly. You never know who designed the aftermarket stuff. In the least, they seldom have the budget to do the extensive testing to make sure the stuff works under most circumstances.

As far as the computer, it should be water tight. You can pull it and look if there's a vent, I don't think it has one.

Another place to look at is design of the new jeeps. I don't like their quality, however, they have an option from what I understand for jeep capable of water crossings from factory. I would be cool to know what parts are different on that jeep and if they can be purchased for our trucks or similar retrofit.

Trying to find it. I took my Tahoe in a canyon. Then a Monsoon flood hit. I had my gopro on the windshield and filmed it. The road was the drainage. It got probably a foot deep or more and I drove through it for a few miles. Happened to me a few times. This was all with the stock air intake.

There was another section I encountered around that time. a probably 30 foot section of road flooded. Where the creek crossed it. It was a GOOD two feet deep. The water was VERY swift (around 30' waterfall a short distance down creek). I was too nervous to cross it but stock light duty trucks were going across.
