I have read a lot of manufacturers claims that high output coils will increase HP. Has anyone fitted these and if so from whom and was there any REAL differebnce?

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.

Its possible they would improve on a GT as its so powerful anyway, my guess from reading this is that on a 380hp car its not worth it
