Motorcraft AGSF12FMF6 Spark Plugs

[Bob Ayers]

I have 102K miles on these plugs now, and tried to find another set. My local Ford dealer didn't even have a listing for them (I bought my first set from the same dealer). I found another dealer online that said they could order them for me:

These plugs have run so well, I wanted another set. Once I replace them, I'll take photos of the old ones with >100K miles on them.

Same thing with the 6 cylinder plug.

I went to get a set of motorcraft plugs for my 02 six cylinder. The number had been changed by motorcraft. The box still had the old number on it but the plugs have the new number.
I took one of the old plugs out at 100K and looked at it.. I promptly put it back in there and still have the new plugs.
The truck now has 130K on it and runs fine. Original everything under the hood!

Did Ford use AC Delco wires as stocl wires? That is what mine has. I bought the truck about 4 months ago and I have 135,000 miles on it. Curious to know if they are original wires. Thanks

Nope!

Not even a little chance! The stock ones should have had FORD written on them..

Well that is good news, now I wonder when they were changed.... I will say, looking at the rest of the truck, it looks like it was taking care of. BUt who knows for sure, right?
