Fill the grill with the largest heat exchanger on the market!  Choose from the single or double wide below.
Whether you're running stock boost on the supercharged CTS V or an upgraded pulley kit, you're already aware of the performance killing heat this engine puts out.   The more dense the intake charge, the more HP your car will make. When dealing with Centrifugal, Roots, or Twin Screw Superchargers, there's always the issue of intake temps as heat is a byproduct of compression.  When running the car hard, you're making a lot of heat that quickly heat soaks the fluid running through the supercharger trying to keep it cool.  Heat results in a loss in power as well as the possibility of damage to the engine. Timing lost due to heat above 140* Intake Air Temp sensor 2 can easily rob even a stock CTS V of 25-50+HP on a heat soaked motor.

One way to help reduce these intake temps and the risk of damage is to add a more efficient heat exchanger to the system that holds more fluid in the exchange area which in turn helps lower intake temps by dissipating heat. This will allow the supercharger to be more efficient while in boost and cool down faster after high boost runs.
