Company's offer a lot of "crap" you don't need. When driving down the road, air is constantly circulating around in your engine bay. Sure it will be hotter than the outside air, but with an intercooler it shouldn't make much difference in the end. The intercooler should take care of most if not all of your "air intake temperature" needs if it is sized properly.
Just because some company builds it doesn't mean it is worth something. Just look at all the crap on e-bay. If you are stupid enough to buy it, then so be it.

I am just saying, in MY opinion, take it for what it is, the effort to do this and risk sucking up water is not worth it for the miniscule temp difference you may see. And on that note, I would be interested in seeing anyones intake temps before and after this install. Using legitimate methods of course. Not just, " I felt my turbo"..
