I can tell you it maintains lower intake temps. than a PMAS. You do need to run a GT350 driver's side breather tube with it though. The bends in the stock coyote tube don't jive with the air box location.
I have one that I have never installed on my 2015 GT - How does it handle water coming into the hood vent? Does it fit okay on to the smaller GT throttle body? Does it seal up to the hood okay?
