As some of you know, I have already had the spark plugs changed on my 2005 Expedition with the 5.4L 3V that is imfamous for them sticking in the head. The dealer did the change and told me they have put high temperature antisieze on the replacements.

The replacement was done at around 65,000 miles, and I know have 93,000 on it, I am thinking about changing them again, to avoid the $2,000 bill it cost me the first time.

Does anyone know how easy the second replacement is? I know the plugs are 100,000 mile plugs, but I want to avoid them locking in again. Maybe I can get by with pulling the plugs, and refresshing the anti sieze. Any thoughts?
