3 Answers


Just need a deep spark plug (5/8") socket. If you have a manual check the gap setting. You'll need a gap tool, which are like a buck or two up at any auto parts place. They might know the gap setting as well. If you want to be technical there's a torque setting for the plugs as well, you would need a torque wrench for that, but most people go by feel. You could also just let a shop do it for a minimal fee.
