After market intercoolers are one of the best ways to lower EGT's with your Cummins powered truck, whether you use it as a daily driver and toy hauler, or are competing with your truck in sled pulls or drag racing. These aluminum intercoolers will show you a healthy 100-150° drop in EGT's and also lowers the intake air temperatures dramatically. This intercooler is built to withstand as much turbo boost as you can throw at it.
