    Just make sure you spray penetrating oil down around your spark plug threads, let it sit for an hour or two, and be very deliberate and slow as you break them loose. Just don't spray too much oil since it will runs down into the cylinders, and let it dry for a while before you install the new plugs. Buy single piece plugs and make sure the block and cylinder heads are completely cool before attempting to remove the old ones.

    He's right. My car is nearly stock, I pulled the factory plugs at around 70,000 the way he said, no problems. I now run the Champion 7989 (only stock heat range single piece plug, the rest are for power adders). I'm at 1506,000 now and cleaned the 7989s once. I will be replacing them soon, but they have been working great.
