Yeah, maybe, it does come from the front of the truck, and some are mounted close to the radiator support, but all have a restriction called a silencer.
Follow the link to see how to remove it and get more cool air into the box:
You can replace the hose that goes from the MAF to the intake manifold with pvc to make the flow smoother and a little less restricted. STL posted a picture of this mod. or, you can go to Autozone and pickup the universal metal/plastic tubes to design our own.
According to K&N's web site, the plastic tubes actually flow better than the metal.
The plumbing department in your local Lowes/Home Depot, and some imagination and foresight will be a good place to start for a high flow CAI.
