Air Intake Valve
A buddy of mine (he is a big Dodge fan and even bigger ford hater) took a look at my new FX4 F150 SuperCab. He actually said that it looked pretty good. He did, however, comment on the air intake valve. He stated that going too fast through high water or even a big puddle could suck water into the air intake valve and ruin the engine. He said that it was a weird place to put it so low to the ground in the front bumper. So is he just messing with me or is what he saying hold some truth (I am not all that familiar with this stuff just yet). Thank you.

First, he darn well better say the FX4 Scab looks pretty good, cuz it DOES!!!
Second, the air intake would not scoop water like he imagines. It's pretty well shielded, and no water could get past the filter anyhow.
And if that doesn't convince him, tell him the old J57's on the KC-135 aerial refueler used WATER INJECTION to boost takeoff power!! Yeah, that's the ticket, it's all by DESIGN (wow, those Ford engineers!).

Back in the old 5.0 liter Mustang days in which I grew up, there were a lot of "ram air" kits that would fasten to the car in the same manner as the F-150 intakes. They would go through the fender well and end up beneath the car.
However, these kits were lower to the ground and sat just below and flush with the front fascia. A friend of mine with the kit drove through a pretty deep puddle and sucked up enough water to get past the K&N filter and into the intake and so on. The car stalled and could not be started and the damage (which escapes me for what exactly happened) was pretty significant and his car was in the shop for a several weeks.
I am assuming the OEM intake from Ford would/could not operate in the same fashion as it would be hard to be a truck and not drive through any water.

Guess I should clarify my statement that water wouldn't get past the air filter...I was referencing cases of splashed water, not submerging the truck in a watering hole or one of the Great Lakes!! 
I think the factory air intake would be OK for fording water no greater than axle-deep...at a reasonable speed (not like something you might see in a Titan commercial!) (that's a shot at Titan marketing, not the truck itself)
