When did Ford stop using motorcraft platinum plugs AWSF32PP and start using AGSF32FM
1997 Ford 150 v8-281 4.6l soh
The differance between the two is AGSF32FM they use now are premium plugs are double platinum tipped . The other plug AWSF32PP they changed is the standard single platinum plug ..
the question was WHEN did Ford stop using plug AWSF32PP not the difference between the two
