LS9 intercooler brick upgrades! Those of you that have pushed your C6 ZR1 to the limit already know that the stock bricks can fail leading to major engine and supercharger damage. These units are a plug and play upgrade for the OEM pieces. Cores are upgraded with solid top and bottom plates, and billet ends so cooler blow outs will be a thing of the past. Testing has shown a 20-30 degree drop in IAT's with no other changes to the car. Further upgrades to the system will only help drop these even more! Sold as a pair.
