I changed the Motocraft Fine Wire Platinum plugs in my Ranger today with 103K miles on them. They were all gapped about 0.062", well beyond the 0.044" spec, but it was still running great.
You can see the effect of opposite polarity spark from Ford's EDIS. The GND electrode is eroded on the passenger's side, and the center electrode is eroded on the driver's side.
