Well, after reading several posts from here, and reviewing the RSB on how to change plugs on my 2005 Expedition, I decided to give it a try.

2005 Expedition 5.4L 3 valve, 72k miles

Well, I got the first one out without much issue. Definately harder than a typical change, but adding the penetraiting oil was a big help.

Second one started well, and was acting like the first. Upon removal, it was only the top of the plug. the shield and the ceramic were still in the head. I put the thing back together and took it to the dealership.

They informed me they have to remove the body, or the engine to get them out.

$1,500 is the estimate!!!!

BULLS#*@!!!

Any thoughts?
