 So you think a regular guy can do it? Yeah, I think so. Yes, sir. So then I guess the next question is... Two things I want to say, though. Okay, make sure you use original MotorCraft or Autolite spark plugs. Okay. Don't go with Bosch or any of the others that people try to sell you at some of the auto parts stores. You want to go with either MotorCraft or Autolite. Autolite makes MotorCraft. Okay, and secondly, you want to make sure the plugs are gapped.
