I never try to go in deep water..maybe this clip will answer part of my Q yah it seams JK can go through such deep water..but what is the limit and did someone try to drive in deep river without modifying his JK?
Yep it can. I have had some water on the inside. Keep the corner of the hood on the passenger side above the water and your fine. Be aware that you need to check all fluids for contamination after a run like that. I have not had a problem with gear oil yet in the diffs, but did drain my t-case.
Have fun out there, but be smart. I would recommend a snorkel if you plan on that all the time.

Driving a Jeep to work makes it feel like you're going camping!
You can run it into water that is about as deep as your fender flares and not worry too much. There is no distributor cap, so it can't get wet like older Jeeps. The air intake comes up to (about) the top of the hood. So, as long as the water does not exceed the top of your hood, you're fine. I haven't done it in my JK (yet), but I did in my TJ. I had water coming inside the Jeep, but with the drain plugs in the floorboard, that is easy to get cleaned up and dried out.
the JK manual page 288 says 20 inches @ less than 5 mph. Also remember if you have a manual trans you shouldn't use the clutch while in water, manual clutches are not water tight and will lets water between the friction plate and clutch plate.

but a snorkel wont solve all your problems... snorkels dont keep electronics dry.
Like others have said, the manual says 20". Ive been over the headlights for a few seconds, just dont get it over the hood or your intake will be sucking in water. Best bet is if you dont know how deep something is, dont go through it. And if you suddenly take a nose dive turn the jeep off quickly and you MIGHT save yourself after you do some things to insure no water is in the engine.
