oh and what is wrong getting the sprak plugs from the dealer... cost about the same and its what Ford would have put in it... i can understand getting higher end spark plugs for a modded car.

RE: Bosch Platinum 4 or NGK?
I used bosch 4 plats on a GT I had before and about a week after I put them in I started having misfire problems. Never again will I use those. I would have to say Autolite coppers from now on. There is a spec sheet somewhere on Mustang Forums that provides good data on plugs. I think it is in one of the FAQs.
