That's correct. Some folks swear by them while others notice no difference. On foxes, dyno runs have shown the stock ignition to hold up to almost 400 HP N/A. Like said, power adders almost definately require a box. Anytime something's done to change cylinder pressures, significant stiochiometry changes, etc, it's a good idearrrrrrrr.parchisi said:Instead of one spark to ignite in the combustion chamber, it sparks several times in rapid succession for a better ignition. Hence, MSD = Multiple Spark Discharge. An aftermarket coil will increase the intensity of the spark. Correct me if I'm off my rocker, but that's what i've been lead to believe.
did you make any other changes with the ignition such as the coil, plugs, and wires? if so, the replacement of older wearing maintenance parts may have been the cause of the noticeable difference.Pokageek said:Makes sense. I have hear the following many times:

I understand that it holds up but can it perform "better"...I am leaning toward getting one considering my personal experience and a few you guys. My 90' just ran better with it, snappier off the line, swept better throughout the RPM range and harder pull to the red line. It was completely stock but for exhaust.
