I bought Motorcraft plugs to put in my truck tommarrow and the part # is AGSF32PM and the owners manual says AWSF-32P is there a difference the guy at the parts store says this is what ford uses in the newer model trucks. My truck is a 2001 so has the part # just changed over the last couple of years or do I need different plugs.

 

We install Motorcraft plugs at the shop I work at it is true that the AWSF 32P plugs have been superceded by a diffrent number I dont have the exact number here at home,lately seems like most of the Motorcraft spark plug numbers have been superceded by other numbers some more than 1 supercision

 

I think the difference is that a double platinum plug has replaced the original platinum plug. I have noticed the G vs. W in the # also.
