I think it's actually AZFS32DP, I believe. The fe stands for iron and the dp stands for double platinum. And you have to get them at a dealership.

Got mine at the dealership for $7.50 a piece, but that was 2 yrs ago. Still look good everytime I pull them. Only had to buy two because the factory supplied the other two.

Yeah i went to pep boys and autozone today and they gave me some 5 dollar apiece autolite dp's. They probably blow goats, but whatever, ill try them and then hit up the dealership sometime soon.

The AutoLites are ok, alot of people run and like them. You have to be careful when installing them. DO NOT crank them down or the insulator will break. A little high temp antiseize on threads will make them easier to get out in the future.

Motorcraft OEM plugs. Period. I have tried 3 different aftermarket plugs, and nothing runs as good as the OEM.

Which is correct and the car should not need sparkplugs replaced until 100,000 miles. But there are alot of people who have changed theirs out for something else.

Are the Iridiums just hype then or do they actually help? I was thinking of trying a set of Denso's...

I used to think something else, but after being on here & then putting them in, Ford Motorcraft Platnum's all the way ...got mine at Autozone though ...can't believe the difference in idle & response.

100,000? I checked mine at 25k and the original equipment was rusted and cruddy - changed to Autolite dp's.
