here is as cold as the air gets, this is what i use works great, if i unhook it i can feel the lose in power big time, you got to find a scoop of some sort, and then cut a hole in the core support(its not as hard as it sounds) then fasten the scoop in there and you can get some kind of aluminum duct worrking and attach to the ats air box then to the scoop or maybe even dryer ducting,
Now im sure your thinking rain is going to get it, nope its not i have never found anything in my air box and i have drove threw down pours then pull my air cleaner off to check, but just in case you need to drill a small hole in the lowest part of the air box if it dont already have one there
