The donor was a 96 Ram 2500 and the OD is large (I can measure in the morning) It is around 4" about the same as a 4 barrel carb. I could probably run a carb filter but I need to have a vacumn line come off the intake also. I think the subaru one won't be big enough.
No problem! FWIW that height probably includes the shank that'll slip over the TB intake as well- it'll probably take some height off it once you have it fitted on.
As to the rest of the piping, when I redid my XJ's intake I used an elbow and then a piece of PVC pipe that I painted and cut to the length I needed. You might be limited to running some kind of cone filter setup though.
I am sure I can find some sort of enclosed filter at the junk yard if needed but I am also ok with a cone filter as long as it passes the smog test. They only other problem I see is that I only have about a 1/4" of lip to grab onto on the intake. The stock one clamped on but I am sure that is something I can easily figure out.
