Here is actual failure . . .
Well 1st hand experience has taught me Beach was right in his theory.
I will take exception to the discusion here. I have the Zoodad mod (over a year) and an Airaid filter (since 500 miles). Started having turbo problems last month, 19,241 miles. Finally stopped working all together, CEL code PO299.
Took into dealer for warrenty and they found the turbo had failed and "had excessive rust in turbo". They referenced TSB 06-23-2, replaced and tested, still not working, so replaced VGT solenoid and reran test. Passed turbo test. Finally replaced turbo oil drain tube w/ TSB.
So, I do think the zoodad can allow excesive H2O into the turbo and the Airaid filter wasn't helping the situation.
End result? Replaced stock air filter to protect new turbo and am considering blocking up the zoodad hole.

How is the OEM air filter getting engine compartment heat and air as some have reported above???
My OEM filter has two inlets... one gets air from the fender well area and the other gets it from behind the radiator support area. None of this air is hot or heated from the rngine compartment however, I do not disagree that "cooler air" coming in through a hole (zoo-dad mod) may not be better... but by how much is a mystery???

Beachbum, You have an 03 Excursion??? I wonder if there are some inlet differences between models or years. There certainly were some aftercooler tube differences.
I have an 04 F250. The only air inlet to the Donaldson filter is at the front of the housing. 1" or so from the core support. All engine compartment air.
Thus, I did the Zoodad mod two years ago. Never have had a moisture issue. Even in the great north wet.

increased mph from 129 to 132 mph. A free 3-5% increase in effiency sounds
good to me. $30-50 over $1000 in fuel (about every 5-6k mile oil change)

My '06 has 2 snokels, the main one extends 2 or inches into the front grill area and has about a 3" opening. The second ones extends to the front frame near the headlight and is about a 1" opening fitting into the frame area thrugh a hole in the frame where it extends too. Also about an inch through the front frame.

As you can see from the post above... there are two inlets or snorkels on the 6.0L motor OEM air intake... or at least on the '03's and '06's??? I am on the road right now, so until I get home on Sunday, this would be the first opportunity I will get to take a digital photo to show what I am speaking of.
Maybe your missing the "hoses" that connect to the front-side of the air filter and route to the two locations discussed above??????
The photo below shows one of the "air inlet" hoses and it is detailed in the "wording to the right" of the photo.
Thanks,

I think the Zoodad mod needs to be tested on Mythbusters. Beach, your right, a stock unit really shouldnt be getting hot engine compartment air unless the rubber between the rad support and headlight mounting panel is gone. All this talk about that little hose has me thinking of a better place to route it 
The mini-Zoodad mod, lol.

The mini-Zoodad mod, lol.I was told by my diesel tech that the reason for the "two inlet hoses" is in case the main large one gets blocked, snow packs in the grill and blocks the grill area, or if a plow is used and blocks air flow.
The two inlets/hoses allow for max air flow and the "sucking in" of enough air for a stock truck or moderately tuned motor.

Ever looked at the stock Donnalson "PowerCore" air filter? It is big, thick and filters very well. My own common sense has me thinking that no amount of "directed" air is going to increase the actual air flow coming out the backside of this HUGE filter.
From what I have researched and read here at FTE, the stock air filter will flow all that this motor needs either stock or with moderate mods.... so if the filter will allow this amount of "free-flowing" air... then how is the Zoo-Dad mod going to actually work... if at all???
To prove my point, the next time someone gets a new filter (or if they have a spare)... I would like to have someone hold either a fan in fron of it and see if they can get some string or twine to move on the backside?
My hypothessis is that the filter is so good at filtering and so thick, that the zoo-dad mod works in therory, but not in reality on the 6.0L set-up and motor.
Even though using the blue synthetic blue media, moisture and dirt/dust make mud.... (at least where I come from)... so even though the filter may not be affected, the dirt trapped in it may turn to mud and mush and "clog" it up sooner???

I believe the zoodad mod is really to get more cold air flow, not more air. With the position of the snorkle, it seems that it would suck a lot of hot air from around the radiator.

All mumbo-jumbo aside i cannot see how having a Zoodad hole saw cut in front of the main intake snorkel is a "bad" thing.
Seriously, all NASA geometry aside, the stock inlet in the fiberglass panel is a tiny rectangle and we open it up a little.
How can this be a bad thing?
Lets email DieselPower and have them dyno test it like they did bio-diesel
