A little anti-seize, not neccessary??!? IT IS NECESSARY OR YOU'LL BE IN DEEP **** NEXT TIME YOU TRY TO EXTRACT THE PLUGS. I've heard too many stories with people having plugs seized in the cylinder head. Trust me, use some anti-seize on the thread, not just a little. As long as you don't get anti-seize onto the plugs' tips, you are fine. You'll be thankful next time because the plugs will unscrew right out.

The 3 plugs in the rear are not as hard as you think. They are easy as long as you are careful.

Some important tips:

- USE ANTI-SEIZE ON THE THREAD.
- Do one plug at a time, don't take them out all at once like the previous person said. You'll be in another deep **** if you forget which spark plug wire (if there are any, 2000+ uses DIS) goes where.
- If you are going for Copper or any other plugs that aren't pre-gapped, make sure you gap them right! Too wide of a gap will cause misfiring and make your car run rich.
- Get a torque wrench with a lower rating (< 80 lb-ft), not one that's rated above 100lb-ft.
- Hand tighten the plugs first with a socket and socket extension. When you can't tighten the plugs anymore with your hand, then use the torque wrench CAREFULLY. You do not want to cross-thread.
