On Horsepower they featured a universal cold air intake the ProFab Quikit. It has all of the stuff needed to fabricate your own cold air intake. The would be very useful if you have an older truck that does not have a pre-fitted intake to install on it. I can't find the item listed on t heir website so I suppose a call would get you the information you need.

I saw that, They ran it down through the battery tray, and had the filter underneath didn't they. Never seen that before.
