If it's stock or stock-ish just replace them with OEM plugs off of ECS or buy them at the dealer. You will need a spark plug socket (the typical size, can't remember it off hand), a 4-6 inch extension and wratchet. Most say them come pre-gapped, but I would get a gap tool just to make sure they are correct. A gap tool is only a few dollars and they should be gapped around .030 I believe.
