I found info here on this forum that recommended plugs include the Motorcraft AWSF34PP or Autolite PP2544 (among others). My local O'Rielly lists the Motorcraft AGSF34FM for my 94 SC. The box calls it "fine wire platinum." Anyone know the difference between the two Motorcraft numbers? The AWSF number was not in their database. They did have the Autolites though.
