Small caps inside the electronics for filtering are good. They also make up part of band-pass filters. Using them to supplement power is a waste. Sorta like putting a bandaid on a broken leg. If you alternator can't keep up, you should put the money towards a higher output alternator.
actually a secondary battery would be a better moved. his stock alternator has roughly 25 extra amps that are not needed at speed. he would see a better imporvement if he picked up a kinetik or a powermaster battery.
