I'm just about ready to drive to the Champion headquarters and fire these crappy 1 piece plugs through the front window. What's the ford part # for the factory plug? I need to get some. These champions wont stop misfiring

 

the champions are made in mexico...did you see the pics i took of mine? what utter garbage. wrote federal mogul(champion) never got a response...gonna send them pictures thru the mail next, almost all of them take the time to respond to written correspondence, kinda suprised though not to hear ANYTHING on feedback for one of their newest products...might try summit too (where I bought them- sure they'll take them back, but I'd rater they just look into fixing quality issues- I WANT a one piece plug, just at 12 bucks apiece expected at least mediocre quality, not they junk I got.

 

My Champions work great and the quality was top shelf. Are you sure you didn't use too much anti-sieze and it got on the electrode? That would cause exactly what you describe.

 

I pulled the plugs and cleaned them all off with Ford carb cleaner, because I was concerned about the same thing. The carb cleaner does a great job of dissolving anti seize. I filled up a plastic cup and let them soak for an hour.

I put the plugs back in without using any anti-seize and got the same problem. It's not the carb cleaner. At least one of the plugs are bad. Since I don't have an oscilliscope to test them, it would be cheaper to just replace the plugs than pay somebody else to diagnose the problem. I got a new set of factory plugs for $7 each.

 

Let us know how that works. Will be interesting to see if it is the Champs or coil(s).

 

Mine work great. Car runs better than it did with the junk Motorcraft plugs, and these will come out in one piece.

 

Same goes for me.
