A number of people have installed an intercooler on an OBS truck. Finding a Superduty intercooler on eBay isn't hard, and they're normally available for around $200. The installation is pretty involved, however. I have a friend that sells the piping necessary for everything to connect properly, and he's installed a lot of intercoolers, yet it still takes him all day, 10-12 hours. Others, who aren't as familiar with the process often take all weekend.
The benefits are that the EGT's will stay considerably cooler, roughly 200° when under heavy throttle. If you've got power enhancements, that would mean that you wouldn't have to back out of the throttle nearly as much.
