C&R Racing's LT4 (Gen 1) flat intercooler brick (CR-UC-SPK005B) for the C7 Z06's & 3rd generation CTS-V's LT4 engine uses bar-and-plate technology developed by PWR's defense and aerospace division to provide THE BEST performing heat extraction available on the market.
Beyond the supercharger intercooler bricks, you should consider upgrading your LT4 primary heat exchanger as well which act as the other side of the heat intercooler system. Together, the heat exchanger and brick setup is the best way to get heat out of a boosted system.
We've done extensive research on C&R based cooling systems and the C&R bricks in particular and there simply isn't a better intercooler brick setup than the C&R solution. More info on our testing follows.
