I have a RJC intercooler on my car and my inlet temps are 123F at the end of my pass when I'm going 154mph. Beautiful piece, and more then likely, it's the last intercooler change I will ever do. I have no AC in my car, but still retain a stock fan and shroud. My temps on the street are still under 175 degrees through that unit. These are also on sale right now too..... http://rjcracing.com/product/intercoolers/product-details/
