Well at 53K miles i've noticed a little engine roughness at idle so i guess it's time to do plugs.

The car's for sale, so i'm looking for just stock OEM replacements...platnium is fine since they are the OEM design.

Have the part numbers changed? I read there was a redsign with more threads on the plug or something like that?

Anyone know offhand the number of OEM replacement motorcraft plugs or Autolites??

I figure i start gathering parts for a full tune up next nice weekend that comes up. I need to do an oil change, plugs, belt and fuel filter as well as rear brakes.

The car is for sale too...and i'd like to not do these things, but then again it is still my car and i'm driving it and i don't want to let things go and get worse as it may be a few months before i actually sell due to it being winter here and snowing

SP493 is the motorcraft number. ford changed the spark plug numbers to make life easier on the parts people. that is the plug with the extended plugs and is a double platnium.
