Help with spark plugs
I have a 2003 Explorer with the SOHC V6 (K). The owners manual calls for a AGSF-22PP plug. Where is the best place to get a replacement? I have found online AGSF-22FMF6. Is this the same plug? It sounds like it might after looking up on motorcraft.com. Also is this a better plug than the Autolite APP103?
Thanks

I'd just go to wally world and pick up a set of single platinum Autolites that are listed in the book as a direct replacement. I just changed plugs and wires in my moms 03' 4.0l SOHC last fall. I got 6 plugs for around $10, it had a bad wire and upon removal it broke so I had to get a new set of wires. No need to buy double platinums in my book, single platinums seem to run better for me and will easily last 40k-50k miles. Make shure to use some nickel anti-seize on the plug threads and change the plugs with a cold engine.(Alum heads)

Single plainums are whats in from factory. They will Easily last 50k. Double platinums are far from necessary and tend to wear stupid in my experience with the spark sometimes just bypassing the platinum altogether. Gap the plug on the low side of the recommend spec to compensate for some wear. The COP ignitions have plenty of power to create a spark when the plugs are even .070" or more.
Last fall I changed the plugs in an 03' 4.0l and replaced the original plugs with over 60k miles on them, the gap may have opened up .010" and those were single platinums.

Ordered
I havent removed the old ones yet but I find it strange that the replacement called for in the owners manual is a double platinum and the factory original is single platinum. I ended up ordering the Motorcraft AGSF-22FM from AutoParts Giant for a very reasonable price as well as the Motorcraft wireset. Hopefully this will workout. Thanks for all the input.

I have never had the alleged problems with double platinums that you describe. The extra stress from excessive gaps is what takes down coil packs.
As mentioned and backed up by several people on this forum with experience, use the Autolite Double Platinums, that way you don't have to figure out or worry which plugs go on which side.
BTW, the double platinums in my Dad's Dakota lasted over 200,000 miles. The single platinums that were used as replacements lasted 15,000 miles. Both plug sets were Autolite.
Also, if you would read the original post, you would see that the owners manual calls for a double platinum plug. For the record, Autolite is a Ford company, and manufactures the Motorcraft brand plugs.
