I have read about alot of high HP mustangs ( like 600+ ) still running the stock ones and doing fine... There are several threads about this. I dont think you would get the gains your expecting out of them on our cars...

i have the moto blue ones on my car but not sure if they made a differance, but i also never changed the gap on the plugs. i have heard contradictory things about the coils, some so called high output coils put out less voltage some higher but for less duration. i know alot of people hate granatelli products and service but their website has a whole video of the coils on a ford gt making more power. check it out and decide for yourself, i went with them just for piece of mind.
