Could someone actually save 5% fuel and gain up to 7% more HP with this or a scam:

Its a scam

i could see it sorting out some electrical issues but hp, torque and fuel gain im not so sure about

[reddevillhs17]

and it looks to me like you could just clean up the grounds you already have and maybe add some more like the kit, and that could sort out some electrical issues.

think i'd try that before i got that kit

Stereo stiffening cap will do that and make the stereo hit hard. Grounding everything back to the battery is the best fix on any vehicle.

I agree with pennyman1 and reddevillhs17 on this. I would not trust that ebay item. You could also upgrade your alternator if You need the extra amperage for a sound setup or extra electrical loads.
