Hello Everyone! I have a 1998 se Bull with the 3.0 vulcan engine (U-code). I want to chage the spark plugs, going with motorcraft. Is there any special tricks to getting the last 2 at the back? The rest look doable. Do I have to use a torque wrench to tighten the plugs? Thanks for any help, I really appreciate it. My Taurus is a fantastic car, has never let me down.
