Asking this question here because when I asked on a vehicle specific forum I got several responses that did not include an actual answer. I got "don't bother" and I got "won't add horsepower" and technical descriptions of the "makes mo spark yo"

So here goes - don't worry about cost, don't worry about whether anyone "should" or "should not" get one... that's not what I'm asking. I'm not shopping or trying to spend money I'm just tired of seeing these things in catalogs and not understanding the point.

On a car that already runs as well as it's gonna run with an OEM distributor ignition system, what would a MSD 6AL actually change about it. If somebody secretly installed one overnight on my daily driver would I notice the next day on my drive to work?

Thanks for any constructive conversation!
