I used an Isuzu NPR cooler on my diesel Dak but I also used a narrower rad so the intercooler inlet and outlet fit nicely on each side of the rad.I want a intercooler real bad just haven't found a good way to do it yet.
Intercooler should be in front of the rad.
Could you send me some pics of your intercooler install. Would love to see it. It would increase the driveability of my durango going through the mountians and when running interstate.
