CAI and Water
Been reading a lot here recently about CAI's. Know very little about them so I have a few questions. What is Hydrolock? I am thinnking it is water getting into the engine through the CAI system, but not exactly sure. Could this be a problem with an open filter type CAI (AF1, AEM, etc): driving in heavy rain, car wash, big puddle of water, etc. Could it be a problem with an enclosed type CAI (SB, Volant, etc.). A lot of you all are using CAI's and I have not read of any water related problems. I guess these things are pretty well designed to prevent any water from getting into the engine. I may go the CAI route and if so it will probably be an sealed type (SB, Volant, etc.). Thought I would mention this because I don't believe I have seen this mentioned before.

You basically nailed it. Hydrolock occurs when water gets inside the engine/cylinders, and since it can't compress it breaks ****. Put plainly.
As for what makes it happen, basically fording a river is what it takes to cause that. Rain won't.

Any intake will (barring a true snorkel), if you submerge it far enough.
Under normal conditions, no. Or you'd certainly see a lot of posts on here relating to that.
Ask Vader - his injested mud into the intake tract while *ahem* vigorously off-roading. Not what I would consider normal conditions, but then I drive around puddles

I have an AEM on my Acura, and it gets air from really low, inside the front fender. I put on what they call a bypass valve, which will not let water get past the valve, should I accidentally drive into to deep a puddle. I don't know if they make one specifically for these truck intakes, but I imagine if your tube was the right diameter, you could insert one in-line somewhere. Of course, these intakes get their air from up fairly high anyway.
