The lower part of the spark plug with the threads also has the 5/8" hex head for the spark plug socket. I've never seen or heard of anyone being able to twist the metal portion of the spark plug apart. Find a mechanic before you end up needing a new cylinder head or used motor!

Chip the ceramic electrode out so you can use an EZ-out reverse bite removal tool. Use a micro vacuum to clean out the cylinder.
If the aluminum head threads are jacked up, you will need a shop that can install a helical fix (typical issue on many Ford engines).
It does make one wonder why ford only has 3-5 threads in the plug wells, and why they continued to sell engines with bad heads.
Edit to add; Not only Ford Triton truck engines, it's also common on boxer engines and overheated air cooled engine jug plugs.

Get an easy out at the hardware store. It is a reverse drill bit. You need a drill that will run in reverse.

Usually when a spark plug blows out, it's just the ceramic core that comes out of the metal case. You SHOULD still be able to remove the case with a standard spark plug socket wrench.

That sucks, I had one break off like that years ago due to super heating in the cylinder from the turbo. Melted the threads partially to the head, plug broke off while I was trying to torque it out. There are multiple tools to try to remove it. Autozone, etc sell spark plug extractors and extractor kits. Another tool called an Easy-Out can be found at auto parts, hardware stores, etc, and is basically a tool that you drill/torque into the busted end of a broken plug/bolt/pin and then back out the original broken part. I think the threads go reverse on the Easy-out, or something like that.
