Properly explaining the issue would help. The spark plug is stuck in the head? like it broke or you rounded it off?

Soak it down with PB Blaster for starters.

Pull the head. (Last resort)

Post a nice clear high resolution pic.
Which cylinder? how old is the plug? using the right size socket? Got any others out, or is this the first one you tried?

Yes I know how to remove spark plugs ! I changed 3 already but 3 won't come out ! I think they might be cross threaded not sure but I can't get them out and I don't want to pull the head

...how does a spark plug get that tight in the head without breaking the actual plug? And I thought the threads of plugs were stainless or rust preventive or something?? Did someone impact them in there?

Let your motor get hot then carefully try to just break them loose..

^^Are you sure about that?^^
Just messing with you.
Just try like the others said. Spray down the plugs wit PB Blaster. Then bring the engine up to temp. Give that a try before pulling the head. Let us know if it works.

1. Overtightened when put in.

2. Bearing down on them instead of just turning in a circle trying to get them out, thereby galling the threads. This happens all the time.

3. No anti-seize put on them when installed.

4. Been in there too long. Carbon fouled on inner threads. Rusted to the head.

5. All of the above.
