motorcraft double platinum sp plugs are available

[Laszlo]

in search of the factory plugs I found these :
AGSP32PPF6 - comes in 6-pack hence the F6 designation. they are not cheap but being a double platinum this is the price - $4.55/each.
If anybody needs them I can get them. I will put these in when finally the engine will be put toghether. after I can comment on qty but being a factory oem they should be fine. I have had an autolite platinum in there and although there was no misfiring it wasn't really good. they also looked horrible after just 20k miles. they should have lasted twice as long. but my failing engine could have been th cause also so I won't say they are bad plugs.

Those are different plugs. The F referring instead to "fine wire." I am withholding judgement on these new generation plugs that have only one platinum electrode. There have been several discussions on these "replacements" as of late so you may want to search on these topics.

Just pointing out that the newer fine wire plug eliminates the need for the double plat format and they are inexpensive at only $3 per plug at O'Reilly's, for instance.

The "F6" designation indeed specifies a 6-pack.

The fine wire plug part number is AGSP32FM.
