No search I'm trying to find which sparkplugs would be the best to replace my stock plugs
If you're fouling out the plug, the one step colder plugs may not be right for the application. How quickly have they fouled on you?I agree. Motorcraft or Autolite OE plugs (platinum) are more than sufficient. If you're modded, go with Motorcraft AZFS-22-C. They're dirt cheap, but they foul out in a hurry.
