I have the manifold off my 2020 if you’re interested

Hey guys, it’s OP’s friend. Found a ‘15 GT manifold off Reddit I’m gonna pick up today for free. The cracking is pretty common in most 15-17 V8s around 60k miles. Hoping this one holds on for a while. I had both IMRCs replaced in what I thought would be the fix to the problem. It was not. Not sure where the crack is or how big it is but based on the symptoms I’d imagine it’s pretty small. No misfires just a little bit of bucking around 2K rpm and a little roughness with a cold start. Threw codes P2005 and P2007 I believe which is IMRC stuck open and closed. Didn’t want to deal with the dealer on this but I have no choice. Took it to mavis tire for them to work on it and they stiffed me $3300 and didn’t fix the problem.Seeing many threads on here about the S550 intake "crack" - does anyone have any pictures to share to show the exact area of the crack and how bad of a crack it is?
Is this "crack" being associated with the IMRC, or is the damage from the crack elsewhere?
Mine’s getting about 5 fewer MPGs. It’s drinking fuel as wellI found mine was leaking by looking at logs. It was adding 30% fuel everywhere. So I may or may not be able to see the crack.
Why the difference in part number then?'15-'17 GT intakes are the same.
No clue. Typically an intake manifold always carries the 9424 number, I've never seen one like the first one.Why the difference in part number then?
FR3E-9S455-HB vs FR3Z-9424-N?
I think I remember some small difference 17 vs 15-16) having to do with vacuum hoses. It affected the installation instructions for PP3 on my 17. I don’t remember details but Ford Performance may be able to tell youWhy the difference in part number then?

Do the vacuum hose differences prevent it from being installed in this current application / situation?I think I remember some small difference 17 vs 15-16) having to do with vacuum hoses.

FR3E-9S455-HB is molded in or is on a label in/on the intake manifold correct? This is the engineering part number (the "E" in FR3E). FR3Z-9424-N is the service part number.Why the difference in part number then?
