Wouldnt what the manufacturer recommends be the best? Even aftermarket?

I always thought it was common knowledge that Mustangs runs best with Autolite or Motorcraft plugs?

I have tried many differenet plugs in my Mustang;
Autolite
Champion
Motorcraft
Bosch
Bosch Platnium 4's
NGK
Delco

For some reason I always end back up with Autolite 25's. They just seem to run better for me, plus it saves the wallet when I change my plugs every other oil change.

I run Autolites as well.

Some good comments here. I am in the same situation of needing to make a decision for the 1st set of plugs in my Cobra. I tend to like to stick to factory stock parts, but I do like platinum plugs (mostly because they seem to last longer and changing spark plugs more frequently than I have to is not tops on my list), and I have tried just about every brand listed above at one time or another. But then, I do not race the car on a regular basis. I did get a deal a few years ago and purchased a set of the Denso Iridium plugs for my GT fairly cheap from an Internet company no longer in business. They were nice plugs and ran fine, but I would not have purchased them for what I normally see them selling for. The choice is yours, and there are better things than spark plugs to spend the extra $ on. For street use and occasional racing, you probably would not notice the difference vs Autolite or Champion. Good luck with your decision.
