Motorcraft SP 493 gap
I'm replacing plugs on my 94 3.0...I had replaced them about a year ago with auto lite plugs but now I wanted to use OEM plugs...I couldn't find the original OEM plugs (AWSF 32P) but after a trip to a Ford dealer found out Ford replaced them with Motorcraft SP 493 so I went to advanced auto and purchased them but when I got home discovered the plugs themselves read AGSF 32PM the gap on these came much larger then the .042 - .047 recommended for the original plugs??? Should I re gap them to original specs or leave them the way they came at about .052 ???
