Get some NGK's I like them in my RS. Make sure you gap them first, and don't put them in backwards (in reference to title). ;)

the swivel head socket works wonders and youll need some extensions..

Deebo's right. Check out the thread he posted. I believe there's a list of tools you'll need for the replacement too. Deifinitely get an extension, too. I think the one I used was 6".

Spark Plugs come Pre-gapped now. You shouldn't have to gap them at all. Not a bad idea to check though.

ALWAYS CHECK!!

+1. They tend to mess up A LOT.

Check unabombers manifesto >>> Spark plug FAQs. It discusses in detail the types of plugs and their application. 1 step colder iridium might be a good why to fly based on his mods.

I had to remove the air cleaner box and the windshield wiper liquid tank to get at the cylinders. After that it was pretty easy, it would have been a lot easier if the car was cold as it is kind of a squeeze for your hands. Just take your time and use anti seize on the threads and dielectric on the wiring connections.
