It uses the ac system to cool the intercooler system. Keeps iat2 temps down to about ambient temps idling in summer and about 10 degrees cooler than ambient driving. By far my favorite modification.
How much cash do you actually need with a partial trade? I have an 03 Mach 1 that is getting a freshly built motor as I type this. I would value it just under your asking price but really willing to work the cash on my end because I really need/ want a truck. PM me if interested!
