it's a true cold air intake (outside air), and yes I did notice a significant bump in MPGs from my previous intake that took air from inside the engine bay.

not totally, but you'd need to fins something else to bend to connect the piping and the cowl opening and seal it up. The stock intake tube works perfectly for this
Just an inquiry but why move the intake to the cowl? Granted the tube is somewhat protected from water but if your engine doesn't stall from water deep enough to effect the stock air box then if even deeper water goes over the hood it's going to be able to enter the wiper cowl and pour into the new tube which is not much higher than the actual air box.

Its not about it being a snorkel so you can sink your rig deeper in water. Its about it sucking in clean colder air from outside the engine bay. Colder air = more dense = more horse power = increase in miles per gallon.
I did read somewhere that the stock instake tube's ribs cause a turbulence effect in the intake though. Smoother air flow, the easier even more air can flow in and at a faster rate right? I would try smooth wall tubing if possible. Enough to notice a difference? Possibly, possibly not.

the new intake location is WELL above the stock location, and much further back. One of the major concerns with these trucks is that the stock box takes air from right behind the headlight. Even going though a large puddle will cause a wake of water to splash the grill and headlights, and possibly enter the airbox.
I can now confidently ford water up to...well...my cowl if i'm going slow enough. I've only managed to have water come up over my hood even close to entering the cowl area, and that was crossing a river. Even then the box didn't get more than a few drops of water in the bottom.
I'd like to see you confidently do this with the stock airbox intake...

I just did this mod. Second easiest mod outside of a front spartan locker.
By the way, great music
