Joe, my thoughts exactly! But, here in Tucson, we have many dips in the road that fill with water if it rains (admittedly rarely). The "low down" intake without a vacuum break (provided by the "Y" in the reference Longshot posted) would guarantee water into the cylinders.

Now, with the vacuum break, the water would probably not be sucked up at city speeds. But, you hit a big puddle at highway speeds (or the vehicle in front does) and you have big water drops at high velocity going into that intake. I'm not confident that they won't find their way into the engine. Personally, I think a "ram" intake needs to be on top of the hood.

Even then, I'd want some kind of water separator. It's possible, as you probably know, to "drown" a jet engine in a heavy rainstorm. A recip would just be destroyed.

I had the 3-way connector in mine, but I ended up taking the "ram-air" out after a while, I didnt notice any difference without it at all. I did notice that my filter didnt get bugs stuck in it, but the filter sure needed to be cleaned after 10,000 miles of the ram-air. That filter is for sale actually, it is a drop-in K&N, it seemed to flow better than the regular filter, and with the K&N i noticed that the truck responded a lot quicker to throttle inputs.
just my 2 cents on the subject :D

Custom cooling
 

i did something similar to running the tube longer to get it farther away from the heat but heard from some people the farther the run the harder the engine has to pull in the air i dont know about that theory but i kept it in mind so what i did is purched a 3inch inline fan used to cool brakes or pull fresh air into the cab of rally cars it only cost $14 on amazon with that i bought a plastic flex line that i ran from the rubber shroud on the left side of the radiator to the k&n filter with the fan that was put inline that fan produces 135cms and ive never seen my aitake temp go a degree over the outside temp and to make it work with rain its hooked up to a switch and the ingition so its never left running when the truck is off

Cool, now just don't go WOT because even the 4.6L engine can pull nearly twice what that fan is able to push (meaning it starts to become an impediment).

its not directly hooked up to the intake its just moving the outside air to right were the filter is on the k&N cai and like i said in my last post didnt know if that thory was true just what i was told but thanks for clearifying
