Alright SN.. I think it's time for a plug change for my Mustang. I have no clue what kind of plugs, other than getting exactly what came from the factory.

What kind should I get? Why should I get them? How much should I expect to pay?

Come on Stangnet, help me out! :SNSign:

Yeah thats what i was going to say. Here is some stuff from STEEDA. They have 8mm and 9mm wires...but i have NO idea what mm we have stock...

In another 10k miles, i'll probably be doing the same tune up, but i think i'll be just going with the factory Ford Motorsport stuff. I haven't decided yet...

Here are some tips:

-blow out the plug wells before you remove plug
-do not remove fuel rails
-clean and condition the COP rubber boots with 303 Aerospace Protectant or silicone spray
-use silicone dielectric grease on electrical contact mating surfaces
-torque plugs to spec and check them in a couple weeks
-use Motorcraft AGSF-32C spark plugs gapped at .054

Platinum lasts longer than copper but has a cooler spark than copper.

I appreciate all of the help guys.. Keep that info comin!.. Not only for me, but for others later on down the road that actually might use the "Search" function

Thanks for those articles Killy!! I'm glad I got to see the different conditions of plugs, I never really knew what to look for til now. And i'm glad to say that mine are like the "Normal Conditions" plug, even with my advanced timing

Yup, I switched to copper at 30K and will continue to use it. Stock gaps is .54. Mine are gapped to .45
