Here's a picture, circled in red is where the Fox's get their EGR gasses from:
I'd recommend running some kind of water through it. A trick setup would be a little stand alone pump and resevior system. wouldn't be that hard to fab up. Or just leave it off. I've run without them before and didn't see any real problems.
The tube in the back can be cut from the little blocks that bolt to the block, reverse them, and bolt them back up. So the solid side will be against the heads.
The fox has a nipple on the heater tube, and a nipple fitting that screws into the back of the lower intake. And it's not for icing, or are you being sarcastic?
I always keep mine in the air intake. Since the air in the lower intake is at a higher temp, the computer won't know what to do with that information, so a tune will be in order if you relocate the ACT to the #5 runner in the intake.
what I did before was drill a hole and use a rubber grommet that the ACT sensor fits into snuggly.
There you go! Sounds like a plan. I gotta figure out how to modify this Explorer TB I got here and I'll have a Fox style 65MM. I have a smaller bore EGR, but I may have it bored out to match if it's not too much money.
