Just saw a commercial for this. Must be working on the P.T. Barnum theory. $69.90 and free shipping. What a pile of crap.

So you plug a capacitor into your lighter socket and your car gets better gas mileage?


It makes sense that it could clean up some electrical noise in your vehicle, but that translates to significant fuel economy increases?
