A capacitor wired across the 12volt DC power to the MSD would act to resisit or dampen voltage fluctuations or spikes.

The benefit might be longer box life but I doubt it.....More stable output possibly by a small amount....

If it was necessary every MSD would have one or come with one but they don't.....
