First, is the engine cold?...must be completely cooled down before taking out the old plugs. Torque new plugs to 11 ft.lbs. No anti-seize if you're using NGK iridiums.

They should provide a little resistance at first. Once broken loose they will be super easy unless they are cross threaded or were over tightened.

How many miles since they were installed?

Aluminum head, steel plug and no anti seize will make the plugs tough to remove because of galvanic corrosion

That's "old school".

Plug manufacturers now plate the threads with a plating compatible with aluminum. Google NGK.

Does hurt to "toothbrush off" the plug threads? (not wire)

Good to check it all out. I could be something as simple as an injector that varies in flow from the others. Keep us updated.
