I will disagree with everyone here...
I have them on my Scat Pack and saw a noticeable change, is it more powerful? Prolly not
What I saw on my stock tune car was better throttle response/less delay. The RIPP Coil Packs are heavier than the stock coils. Coil packs are essentially a capacitor to deliver spark to the plug... heavier means bigger capacitor, more power to deliver the same or more juice per spark for longer.
My story, there is a ramp I use to get on the highway everyday, sightlines are terrible and I have to get into the merge lane before seeing if I will be able to merge... There was enough of a delay with my old setup that it cause me to under accelerate onto this 55mph highway... NOT ACCEPTABLE from a 6.4L Muscle car...
I added the RIPP coil packs and have not had that merge delay since. That is tangible proof for me that I made the right choice.
