Spark Plug: AGSP-32PP is the factory plug. AGSP-32FM; is it just a replacement? Or an upgrade? Is it good?

double patinums are not stock. the F means fine wire, the finewire is a better design overall than the regular Pt 'puck' plug.

The AGSP-32PP was the stock (double paltinum) plug that Ford put in all the GenI-GenII SHO's. They discontiuned them about 2 years ago. You can still find them around if you look hard enough. Ford replaced them with the AGSP-32FM, which is a 'finewire' plug. It is made for the SHO application. Many members are running them with no problems - however we have yet to see if their longevity will compare with that of the AGSP-32PP's.
If you are looking for new plugs I would certainly go for the AGSP-32FM. I would make sure your plug wells are clean (don't let the oil go into the cylinders!) so that the oil doesn't destroy the new plugs, and wires (if you are doing wires).

right, don't pay more than $6 for a plug for agsp32fm as they are almost the same as autolite 3924xp's. they sell those at advanced auto I believe.
