Default cold air intake questions

i am a bit of a diy'er and have seen some other threads detailing how to make your own cai. i have an 05 quad cab 4x4 with the 4.7. having a blown mustang i don't have this truck for a "need for speed" but am interested in doing anything i can to improve fuel economy.

my question revolves around that "box" that's attached to the intake tube that seems pointless. first and foremost, what is it's purpose? and secondly, what will i harm if i make my own like other's out of PVC or the like and replace the tubing.

i will likely keep my factory air box as i like the fact it's fender fed and there probably isn't a significant benefit to changing to a cone style filter. i'll likely slap a K&N in there and cut everything but the supports for the bottom half of the filter off lol.
