    At 75 thousand miles on a set of plugs, it's probably a good idea :eek:

    Huh????????.... False!!!
    I just use a very "light" coat of oil on the threads and torque the plugs in to specs...

    I've heard the same thing, I pull the plugs out of my wife's truck every 100k and add some new anti-seize compound to the threads.

    (they don't need to be changed at that time, just cleaned a little bit and put back in)
     

  5. Huge problem with fords.
     
  6. If the plugs were prepped properly before the install, and torqued, the answer is NO. If you are referring to a O/T late model Ford product, -YES. The original plugs are a 2 piece design, and quite often they will give you problems taking them out. The aftermarket has already addressed the issue. Good/knowledgeable late model Ford techs should have the kit to remove the seperated pieces of spark plug safely, TR

    Antisieze is a must (not oil). Copper based (aircraft) is best as it stands up to a bit higher temp. Loctite C5A is example
