I read the DIY Charge Air Cooler article and generally followed it for the most part.
I modified plumbing and did the install to suite my truck. I had previously installed large aftermarket oil cooler lines... and therefore needed to place the intercooler lower under the bumper due to inference.

Cost was approximately $475
I haven't dyno'd the truck yet but it has noticeably more pull...
I'll be fabing up an intercooler guard to prevent banging the thing. It is in a horrible spot... be we work with what we are given.
