Hows your water temp? and your A/C cooling? I am looking for the same setup but I am affraid the AC condenser and radiator cooling efficiency will be affected becuase of the G3 and the oil cooler.

All my temps are great along with the AC. I don't see any reason why any of these products would effect each other. Also I have remove the opening in the front clip to help a little more. Not that it was needed. I'm going to be running some duct lines for my brakes soon also.
