You want colder air pre turbos in order to reduce duty-cycle, and run the turbos at a better efficiency for more boost.

Gotcha. So it's the best of both worlds: A more efficient intake tract for less work by the turbos but with the colder, denser air of a CAI.
Are these the ones you're referring to? Seems like a lot for some silicone tubing, no?
