I've got one. Install wasn't too bad, had a hard time getting the bolts in the box due to not being able to fit my hands in the small area...if you have one of those flexible screw drivers it'll work just fine.
Yep, thats what the big box hanging off the stock intake pipe is for.Lol, i forgot about that bolt! It is kind of a tight fit but manageable. The fit and finish are top notch and all the bolt holes line up where they should. The instructions didnt say how to attatch the rubber seal to the air intake- it goes on the intake, not the truck body. I think some people struggled trying to put it on the truck body. None of those issues were a big deal and would not deter me from recommending it. The CAI Really dresses up the engine compartment and adds a throaty sound to the engine under acceleration. I was actually surprised at how loud it was under WOT, it sounded like an after market exhaust. I guess the stock airbox has some sort of anti resonating chamber or something?
