Question about 2004 Ford F150
If the base of the plug (with the part that fits into the socket) is still in the head, you need to soak the area around it with wd40 and turn it just like you are removing a normal plug. Once it begins to bind, run it back down and start over, each time attempt to go a slight bit further.
Patience is essential as likely there is a carbon buildup on the business end of the plug that can tear the threads right out of the cylinder head. It is also possible that the last person to work on it cross threaded the plug into the hole in which case unless it is very accessible the head will need to come off to be repaired anyhow.
(can be repaired using a heli-coil). I don't recommend the use of an easy out to do this job as most are essentially a reverse thread screw. A screw is a wedge and when installed, it will drive the sides of the plug against the head even harder.
Since tune ups are infrequent compared to how they used to be, regardless of if your heads are steel or aluminum, it is essential that you use anti-seize compound on the threads of the new plugs to prevent this from happening again. Good luck and be patient! Hope you don't need to remove the head!

Using an ez out will remove it better.A very small one will do installing the EZ OUT through the Electrode's center
