I can make you a short ram intake, if your interested for your truck. Def. cheaper then buying one even off ebay. Will come with filter, pipe, clamps, couplers, and the breather filter for the blow-by tube. I did it on my truck already and it works great.

I am working now on doing a full inake, that does away with the big box right over top of the engine, but still uses the stock mounting hardware, so you need nothing extra besides the basics (piping, clamps, couplers, breather filter, filter, etc...)
I also just put a Flowmaster 50 series dual exhaust on the truck, def. can feel a power increase, not sure on mileage as i just did it yesterday, so ill fill up today after work and see how it does on mileage. I know just my short ram increased my mileage, so im pleased so far.
