I know this Motorcraft plug is NOS in most stores AWSF32PP, but if you know where to look you can still buy them. The OE replacement is AGSF32FM. Now, which is really the better spark plug ??? I`m put new plugs in my 97 4.6L V8 F150. The first is a double platinum, the second one is a fine wire single platinum. So which is better???
The only difference is that the later number has more threads than the OEM number. Fits the same and still goes in the head the same difference, it's just a revision so that the plugs will also fit the mid 02 and up revised heads with 8 threads as well.
Use the AGSF32FM.
ok, i bought these plugs for my 97 grand marquis 4.6 and never got them in, with 54 k i traded the car in nov 07 on my 07 f150 4.6
build date 06/08/07 norfolk plant
