Re: Ford 5.4L Triton V-8 spark plug change

I have seen several people change these plugs and NOT use OEM plugs, then they run ruff! Motocraft is the ONLY plug to use! #4 has a habit of spiting out the plug threads and all (happened to me) ford has developed a tool to recondition the head without removing it. If you have problems on the crank it is most often (again) #4 that goes bad,,,,
