I am waiting now on a digital manometer so I can do in car on road testing of pressure drop, I could probably setup a twin IAT setup that is similar in design to check out the temp differences as well in real world situations.

The one thing about this that you have to always go back to is just the laws of thermodynamics, it is proven beyond question that aluminum is a better thermal conductor and SS is a better thermal insulator, the IC needs to be a conductor to transfer heat in either air to air or air to liquid configs, the piping is a conduit for moving the air and should be an insulator so it isn't effected by external thermal impact and if it is, a metal with better insulating properties will transfer less of that heat into the internally moving air regardless of the temperature of the pipe's material. If it effects the air moving through it to a noticable degree is the question I think is most relevant. I will find out so there is no longer a need for wonder. For now I am still going to lean toward the side of logic and thermal dynamics and believe that it is worth taking the extra steps for the best possible scenario.
