I'm doing a spark plug change on a 2005 Ford Explorer with a 4.6 V8. I got all of the plugs changed except for one. This one is apparently stripped. The plug is loose and you can easily turn it by hand, but it won't come out of the cylinder head and is stuck. I can keep turning and turning it but it never comes out. I tried starting the engine, hoping the compression of the cylinder would make it launch out with no luck. Any ideas on how to get it out?

Are the cylinder heads aluminum?

The plugs are deep down in wells. You can't get a welder down in the well.

I'm not sure, they probably are.

The 3v started in 2006 in the explorer. Don't believe this is a 2 piece plug issue.

I don't have the truck in front of me right now, but I think I remember seeing "4.6 24 valve" on the throttle body. Which would make it a 3 valve. But these plugs don't look like the weird 2 piece plugs that are known for breaking. They look like normal plugs. Also, the whole plug is spinning in the hole. It doesn't appear to be only a broken piece spinning.
Btw, the plugs that were in the there are Motorcraft AGSF32PM. The new plugs are also Motorcraft AGSF32PM.
edit: Never mind, it doesn't say "24 valve" on it. It says "4.6 SOHC." So it should be a 2V.

If it is a 2005 it is a 2V 4.6L, 2006 and up had the 3V 4.6L.
Post a picture or describe the plugs you did successfully remove.
Long nose pliers (doubtful you can get them all the way down to grab it) or JB weld epoxy putty (not the regular stuff that can run) a cheap throw away plug socket on it and pull up on it while rotating in the direction of removal is all i can think of at the moment.
It unfortunately sounds like stripped threads in the plug hole. Even if you get the plug out you may not be able to screw another plug in. You can try and see what happens. Otherwise you're looking at doing some sort of head thread insert.
