Got mine for 70 bux with all the rails, sensors, TB, IAC, ect...
Mine was painted... It's a silver paint, not as gray as the older 5.0 intake paint.
The TB must be modded. The throttle arm is not oriented correctly for the HOs.
Couple of other little things too, don't recall them all... but I remember the rails weren't right either.
Depending on the year, you could get the better 4 hole 19# injectors... but IIRC some of the later ones use the different plug, meaning your harness won't plug into the top of the injector.
Some other variations between years are the internal and external EGR plumbing as mentioned, and the placement of the IAT sensor. Some have the boss for the IAT, but you have to drill and tap it. Easy cheezy, so long as you are expecting to do it, and don't find out it needs doing AFTER you have installed the lower.
We used the heater pipes for our application after some modding, but for a stock for stock swap, I assume you would prefer the Fox pipes. There IS a difference between them.
Another observation...
Why does everyone leave that 'ear' stuck off the side of the intake when they swap?
I think it bolted down a bracket to anchor a cable? Throttle linkage?
It shaves right off in seconds... Leaves a nice clean look.
The pic shows the intake without the 'ear' on the side, and the red shows some of the silver paint flakes that didn't want to come off.
That is some TOUGH paint.
