intercoolers on 1st gens?
Up to around 2002 or whenever they switched from the 7.3 to the 6.2 or whatever it was. You should upgrade all the plumbing, tubes/boots, to match the I/C's in/outlets - 3". Why upgrade the cooler if you are not increasing the capacity of the plumbing to match?
I always use exhaust pippe for teh tubes and these guys for teh couplers
