Got a CEL with a Cylinder #2 misfire Friday night so I figured it was time to replace plugs and a coil pack (was planning to do this later in the summer anyway). The rear two coil packs are a PITA to get back on and you really have to feel around to get them properly seated.
I did run into a problem on the rear passenger (cylinder #3). There just was not enough clearance to get the coil pack out. I tried, and I had someone else try. We rotated 180 degrees, we tried going up, down, and towards the front , as well as various angles in between. I ended up scratching up the valve cover pretty good from trying to wedge the coil pack out. I know the XT has a bit less clearance than the LGT, but it was stupid tight and I gave up after fighting it for a couple hours.
I did want to add that I picked up a Gearwrench flex spark plug socket that worked for me with either 1 or 2 1" extensions. I know people love the Snap On one pictured here and it looks fantastic, but this was about 1/6 the price at $12.
