I'm about to replace the spark plus in the car. What does Ford recommend the gap to be at with the new plugs? I'm getting conflicting information. Some are saying 1.3mm, others 1.0mm. Some are saying originally Ford made them originally to 1.3mm but this caused the coil pack to go faulty. Ford then solved the problem by making the 1.0mm.
So which is true? Do the original Ford Motocraft spark plugs come with a gap of 1.0mm or 1.3mm? The NGK's is was about to buy come with 1.3mm?
