haha do i need a torque wrench? and how do i gap the plugs? etc.
and a lil side question.....how do i use seafoam and does it clean ALL my internals including injectors?
You need a normal socket wrench with a socket for spark plugs, all parts stores sell them. You'll also need a gaper tool, it's a little ring with measurements on it that you use to gap the plug. Almost all parts store sell them, just get an employee to show you how it works, very simple, just be careful and take your time.
Don't know about torque specs, but I just tightened mine till they were snug, not tight tight, but not loose either. Point is, you want them to be tight engough to stay on, but just loose enough to easily come off. I say tighten them till it gets hard to tighten them, like when you can only go between 1/8 and 1/4 turns ,when you hit that point, stop.
