My "problem" was getting the coil packs unmounted. I got a 2010 and I've got three of these(I know it says 4.7L)
The mounting bracket holds an anchor with a screw in it. Found out you just gotta get a big flat head screwdriver in between the anchor and the anchor hole on the engine and pry it out.
Putting it back in is just taking the screwdriver and tapping the top of the anchor so it'll pop back in the anchor hole.
