Well, it came with the truck when I bought it and I was told that it was a KB intercooler but I am not sure if that's correct or not. There are no markings on it identifying who made it but I saw one similar to it somewhere here on this site a while back and I just can't remember who made it... :dunno:
Looking GREAT! The IC is an early ATR one with the "grill" top. The later ones had a "checkered" top. The corner of them are known to punch holes in the cover for the blower motor. Keep an eye on how close it is down there...
