I have the Perma Cool type and it has worked great. I really don't need one here as hot as it is during driving season, but it came with the kit. I mounted mine on the left hand front side of the car across from the radiator and out of sight fromnabove. Not trying to hide it but that was just the easiest place to put it between the filter and cooler. It isn't nearly as nice as the billit ones, but it also didn't cost so much.
