There are many units out there, including remote mount/dual mount filters. There isn't alot of room in the bay to work with and you don't really want to put it in the air flow of the radiator and condensor. This would compromise their cooling ability. I really don't think there will be any true gains by using a cooler. There IS one spot that you could use if you got a small unit. That would be the left/driver's corner under the bumper cover, remove the cover and you'll see the room you have. I would have put mine there. http://www.jegs.com has many units that are small.
