Spark plug won't come out.

Thanks for the help everyone. i used my PB Blaster and rocked it back and forth and it eventually came out. The new one went in just fine. A good thing since two more were difficult as well.

Very happy it worked out and I got all of the tubes and o-rings changed. One plug was covered in oil since the tube was cracked so it was causing a sputter. Now everything is nice and smooth.
