[QUOTE="Yardsale , post: 1025161, member: 58988"] Those gap specifications are correct. 1.32mm/(25.4mm/in)=0.051968in, 1.42mm/(25.4mm/in)=0.055905in. I could not find a wire type gauge that wide and used two flat feeler gauges (0.030 + 0.024") back-to-back to set at 0.054" The AGSF-22PP has been superseded by the AGSF-22FM. I tried to find the 22PP, but could not. The difference is that the 22FM is not a double platinum and dose not have the spec of platinum on the ground electrode. Autolite makes a double platinum, but I shied away, bending to Internet pressure that Autolite plugs are not necessarily made to Ford specifications. Recommended spark plug replacement interval is 100,000 miles. Unless there is a problem related to ignition, my experience is this is a good recommendation. On a whim, I replaced my last set with about 40,000 miles on them and they looked about new - light tan in color with no center or ground electrode wear and gaped as I set them. There was no need to change them. I'd pull one or two of the easier to access and check before I put myself through the pain changing them. [/QUOTE]
