Hi guys can anyone tell me anything about Positive Charging System/Voltage Stabilizer what it is, what it does and how you connect it? I found one its marked bmw/ac schnitzer but not really sure what it does and if its worth buying.

Hope to hear soon!!!!

it's supposed to remove any power fluctuations from the car's electrical system that are caused by the alternator.

The ebay seller probably mentions that it will:

add 5-10hp
better throttle response
better acceleration
fuel economy
more torque

I assume that it has a big 4-5 farad capacitor inside or some kind of transistorized filter.

if you ask me it's a load of crap ;)

An actual voltage stabilizer, actually... stabilizes voltage, this is for places where there are huge voltage fluctuations, such as power surges of more than 25v (in a 110v system). Over here our voltage is 240v and I've seen peaks of 260v.
