He's right, those thingys are small capacitors, they filter out high frequency "noise" that the alternator generates, which can help with radio reception/ amp noise from your stereo/etc.
That being said, I've never had one on my dsm, and my current radio can pick up all the St. Cloud radio stations from my house in Coon Rapids, so I doubt it helps much.
