I saw a great "How-To" on this somewhere on the net or in here for that matter. I don't remember where it was?? I used it and I got my plugs changed in about forty minutes and a lot of patience! (and cusing!) It's definately a DIY project with all the right tools.

Many of us have chosen either NGK Iridiums or the Denso Iridiums. Both are great plugs.
