Did this a couple of weeks back. 2 Broken, (#1 and #8) that the Lisle tool made short work of, the other 6 came out just fine.

Like what has already been said, don't be shy with the PB Blaster.

does the 04 to 08 take a special plug, and let me know if it helps out the way your pickup funs. thanks

The 3 valve 5.4 uses 2 piece plugs. They are notorious for breaking when you remove them.

Post up on how it goes. I need to get mine changed and I too am thinking about doing it myself.

I found that this helps. Turn it about 1/8 turn, then spray a bunch of sea foam deep creep in the hole. Let it soak in for a couple hours. Be very careful when trying to unscrew them. If it gets too stiff, turn them back in a little and spray more deep creep in. Deep creep works good because it is thin and gets in the threads well. It also won't affect the engine when you start it back up. When you install the plugs put anti-seize on the electrode shield, the part below the threads. I have read that you aren't supposed to put it on the the threads, and I don't, but I don't know if that would be bad on it or not. Just make sure you don't get any around the electrode. Also, you are supposed to remove them with the engine warm. Not hot, but warm. Hope this helps.

If they break, they break when you crack em loose initially. All 3 of the ones that broke on me had dry electrode shields and the truck sat with seafoam in the plug holes for 3hours or so. It is no big deal, the only ones you want to worry about are the back 2 on the passenger side. If any of the others break, you won't have too much trouble. When you push the ceramic down on a broken one, push it until you hear the ground strap pop or until there is about 3/8 of a space above it to let the tool bite in. It should turn into it pretty easy, not a lot of pressure to get it to start.
