Magna Charger

[Fubar]

Your dealer will probably be one of the better choices. I suspect that if you go to some place like superchargersonline (i thing that it) or anywhere else and purchase the unit and have it shipped to you, your dealer will be able to do the install.
Your dealer will have more purchasing power so don't be surprised if they are able to get you the best price, plus most H2 dealers already carry the unit.
