so many different stories about a/c & a 500 cooler, for now i have left mine on a standard charge/intercooler with a pace upgrade. When the weather warms up a bit & get some motorvation i'm thinking of trying to mount a 500 cooler infront of the a/c rad, that way the cooler will have a better flow of air, the a/c will not work as well but it should still do its job!
