ive put on 14k on my champions and the butt dyno can't tell a single difference
still runs like a champ
i'll pull the plugs later this winter when the car is stored to see how they are wearing, but i don't see how big a difference there would be between stock and champions

stick with the factory ones unless they just need to be replaced due to wear and tear. then you can slap in some HT1's. Thats what i have and no complaints.
if you are planning on going N2O or Forced Induction, you may want to go to a colder plug, ie. HT0, Ford Racing, ect.

Some people have installed them and are not happy with them. Some buy a mustang and don't like them. That's them. I remember reading something about the lawn mower dude and he just didn't like champion. He did not have personal experience with them.
10-15 years ago you would never have caught a Ford dude putting NGK (Jap Crap as it was referred to back then) in a mustang. These days, you'll find a ton of threads here on the forum recommended NGK plugs for the FOX body and FI cars. Times change.
And for the record, neither Champion or I claim any improvement in performance vs the OEM two piece plug. I did the swap for piece of mind. Nothing else.
If you're expecting a change in the car from replacing the plugs..you will be disappointed unless your existing plugs are already crapped out.
