Looking at the stock element, I have to believe its restrictive. Looking at the stock box.....I can't see how you can improve on that. I mean, MAYBE you can make a larger volume box (like what roush is doing) but thats about it!
.....yeah that thing, it came with the kit when I bought it.
Well it depends on what you mean by improve on it......with an open air element like the AFE you get more air flow, but its not cold. It gets hot air from the engine, which if you run it hot weather and run the 250 tune, like I do as well as some other people, then you run into a problem with ambient air temp parameter for intake getting high and throwing a CEL. I'm running a different tune for the 250HP tune to see if works and so far so good.
Also please don't fall for the "this CAI pulls are from the side vent" at high speeds that going to act like a vacuum do more harm than good
Really the best thing for the truck would be some type of ram air set-up and from what understand its being looked at and is in the works.....I just hope it looks good
