Spark plug won't come out.

Now I'm completely confused. Here's a quote from the Pelican Parts web site regarding the use of anti-seize compound:

Install each spark plug into the cylinder heads without using any anti-seize compound. Torque the spark plugs to 30 Nm (22 ft-lbs). I recently learned that Porsche, published a bulletin indicating that it doesn't recommend using anti-seize compound on spark plugs for any of their engines (Porsche Technical Bulletin 9102, Group 2 identifier 2870). The bulletin applies retroactively to all models and the theory is that the anti-seize tends to act as an electrical insulator between the plug and the cylinder head. This could have detrimental effect on the firing of the spark due to the loss of a good, consistent ground connection.

I installed mine without anti-seize compound. The change interval on the plugs in my 2000 is 30,000 miles. I'll be holding my breath for another year to see what happens when I take mine out.
