Which Motorcraft Sparkplug ?

I have a 98' F150 4WD 5.4L gas vehicle.
Last plugs installed by dealer were Motorcraft AWSF22E F4
Dealer now suggests Motorcraft AGSF22WM plugs....
Does anyone know which is correct ? or Where can I look the application up online ?
Thanks for the help

My guess is that is the "new" number for the same plugs.

Your original plug has been superceded. The new plug has longer threaded area and higher center resistance.
Unless your dealer or some other dealer has some left on the shelf, they are no longer available.

new plug version

Thank you Bluegrass, Yes , that was the explaination the dealer gave me , and that the new plug was a combo irridium and platinum. So, naturally the part number has changed for the new upgrade plug
