If you're looking to add twice the amount of fluid in the heat exchange area and you're over-driving the supercharger, you can add this single wide unit in front of the Track Attack heat exchanger on yourgen2 (09-15) CTS-V.
Whether you're running stock boost on the CTS-V or an upgraded pulley kit, heat is the enemy of HP. The more dense the intake charge, the more HP your car will make. When dealing with Roots or Twin Screw Superchargers there's always the issue of intake temps. When running the car hard and spinning the blower fast you create heat. 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 radiator to the system that holds more fluid which in turn helps lower intake temps by dissipating heat. This will allow the super charger to be more efficient while in boost and cool down faster after high boost runs.
This unit is a 5 row core that holds an extra half gallon of fluid and measures 36" wide x 7" high x 2.75" deep
Unit comes with attached brackets ready for installation.
Can take 5-10 business days to ship depending upon inventory.
