Another Spark Plug Question- Non COP 4.6

I have read so much about using the Double Platinum plug on the 4.6 motors. My question is which plug do you recommend for the early 98 F250 4.6 non C.O.P. motor. I've searched and can not find the answer. Thanks, Dan

If you can find Motorcraft get them, otherwise Autolites.

The direct replacement for my 01 in a Motorcraft is a single platium. Those work fine.

Should be a SP432 Motorcraft plug.
AGSF32FM is an alternate number. Older part number, same plug.

I just installed Motorcraft single platinum's on my 4.6L. Just go to AutoZone and ask them for Motorcraft plugs, and they will give you the factory replacements...
