i hear its a waste. if you want better ground wires, just replace the ones you have already from the battery and on the engine.

 

they are sopposed to improve over all drivability by adding more grounds and giving some of that power back thats being lost. Some people say its good, and some people say no..

 

I have a Sun Auto grounding system, and although I can't say if/how much a gain in hp/tq bc I added it along with many other mods all at once, I definately noticed a difference in the sound and quality of my system (i.e. less noise and stronger bass albeit a small difference). And my headlights were a lil brighter.

 

In a back issue of Import Tuner, they tested one and actually gained 1.9hp on the dyno. But this was a $200 one. There are better ways to spend that kind of money.

 

It does help since most oe ground wires are exposed wire and they tend to oxidize and corrode over time but I'd not get them for hp gains tho. The set I got was the cheapest on ebay and I used the wiring in that kit on three different cars (only used two or three sections of wire, from batt to motor and motor to fender/rad support/firewall).
