My 98 LS came with fine wires single platinums and lasted only for 18K miles. The rear bank fires reversed ( ground to the center electrode) the bank needs double plat's, only because you can't get single platium on the ground strap electrode only. Even with the double platinum those rear bank plugs still wear faster than the fronts. Been nice to had the coil over the plug COP we wouldn't be having so many problems.
Even with the double platiums after 20k the rears start having minors misfires. Wish I could remember the parameter on Alex Peppers scan tool I used, it wasn't avaiable until a year or so ago. Actually it's a Ford test, Alex's software update made it available. Anyhow I swapped the same plugs front & rear. Ok then. Last summer I did that, having felt checking ugly winter this year. Drivability was never a problem, MPG drops off. 1-4 mpg more for the orginal fine wires.

I just happened to get the Motocraft at Autozone before quite carrying them. AGSF32PPM in 2002 when I replaced them Autozone didn't show this as the correct plug, they still showed and may still show the fine wire? This plug was spec'd for my brothers F-150 w/4.6l and I noticed it was the same exact size , 32 same heat range and double platinums.
Parts guy at my dealer said they will cross and Ford was in the process cutting the number of plugs offered.
I have yet to check but I'll probalbly go with the Autolites soon. I was thinking the size of the platinum dot was tad bit larger than on the Motorcraft ground electrode?
Steve I just checked the Motorcraft link I see they are even pushing the fine wire for the 4.6l. Nothing says there is platinum on the ground electrode??? Or is "F" a single and the "FE" the double????

Fine wire plugs have only been available for a year or two. It is impossible for your 98 to have come from the factory with them. You probably had three single plats and three double plats installed at the factory.
The "fine-wire" plug is the standard for most Ford engines now. There is no longer a requirement for a platinum ground electrode using this design.

Ford started using fine wire plugs on the Duratec in the Contour in 96.
I took Motorcraft finewires out of my 98 SVT at 60,000 miles and installed Autolite double platinums. They didn't really look too bad at 60,000 miles, but I know how bad they tend to look at 100,000 miles.

I'm pretty sure that the 2000 SVT used a plug that is one heat range colder than the rest of the Duratecs. You should have the parts guy confirm that before you install the plugs. There is an Autolite double platinum for that application.

Stick with the stock heat range.
Trust me I know from experience that the 22's are too cold for normal driving.

It was not broke; Yet I fixed it anyway.
