Default Spark plugs

It seems like my spark plugs are welded in I can’t brake them loose I tried soaking them for days and a breaker bar but it feels like if I keep up they are going to strip out ... any help please?

How many miles and what year is you Crossfire ??
I've heard that the plugs can become almost impossible to remove at or over 100,000 miles

The original..... like OEM plugs with nothing but the Benz logo on them are still installed in the 181k mile 3.2 I pulled out of my V8 car.

I pulled a few of them out a few weeks ago and it took quite the effort. Even with the effort, I really didn't expect them to be the factory plugs because the engine ran so good.

I would really twist on them, but your car is not my car.

Good luck.

In our houseboats we would run MMO in the fuel a week ahead of time and then again spray each plug the night before doing the plug change. it worked.

Also hitting it with a impact worked on a car I had, if you can use one that is. the car i used it on was a 2.2 inline four so the plugs were easy to get to.

It may help to remove the valve covers to give you better access?

Yes, it is well worth the effort to remove the valve covers when doing plugs.

They probably had gaps you could drive a bus through, definitely time for a change.
I should loosen mine and retighten them, I do not want them to seize up in place.
