I have a 2018 S6 and have installed a stage1 ECU & TCU tune from Integrated Engineering and the car runs great.I am thinking about upgrading my air intake system to the CTS Turbo Dual 3" intake Kit W/ 6" velocity Stacks.And would like to know if anyone has installed them.

I think if you read around enough you'll see that the intake pipes connected to the turbos themselves are the real restriction. You can see how that system necks down dramatically to mate to the turbo pipes.
All of the other systems that don't directly replace those pipes mainly just offer more intake sound if that is what you are going for.

This might be the only one that at least in theory would allow for more airflow. (Confirmed by tuner.)

For Stage I S6 though an RS7 setup is generally all that is needed.
