Just in case you're not aware, the Hellcat (cars) have an initial heat exchanger (for the blower coolant) on the driver side, about the size of this oil cooler, and then a primary heat exchanger in front of the radiator, about the size a an AC condenser. At one time I was going to use all factory parts, but I've decided to find good quality aftermarket stuff that will fit my car as precisely as possible and have the inlets/outlets where I need them.
