2000 Nav & correct spark plug

I'm about to replace spark plugs in 2000 navigator 5.4L. Serv CD says to use AWSF32P. At local store the motorcraft catalog says AGSF32PM (which I bought). Also at motorcraft.com both are shown depending on how you do a search. I cannot find a description of the difference and which is really correct.

Anyone know please? Thanks

Forgot to mention the AGSF32PM is also known as SP493---not sure what the SP # is for the other plug.

I changed my plugs a few weeks ago and seems all the #'s have changed over the years. Go with whatever the books call for these days.

Well they are both correct for your Gator . But it all depends on which motor you have.
If you have a 32 valve motor you need the AWSF32P . And for the 16 valve motor you need AGSF32PM.

2000 models only had the 32V 5.4L.

I sure don't know which is right---the motorcraft catalog says AGSF32PM for the 32V Nav engine! I thought the 16V Expedition engines used a plug with the number 22 in it.

Guess I will have to call the dealer---I have not found anyone that sells the AWSF32P plugs--so I assumed the motorcraft catalog was saying the AGSF32PM replaced it.

Confusing to say the least
