I have the kit on both my 94 Cobra clone and my 95 GT. How much of a difference you notice depends on the condition your ignition system is in now. On one that's in good shape, you may not feel much. What I mainly noticed is that the engine now pulls hard all the way up to redline. With the stock parts, acceleration tapers off a bit as you get in the higher RPM's. That's my experience, anyway. I have never put the cars on a dyno, so I can't say exactly what I gained. But IMO, the kit was well worth it. If you're looking to save money, I would buy at minimum the Screamin' Demon coil. I noticed the biggest boost with that one part alone.
