VtecRacer: IF your OEM grounds are poor, then yes this kit would help you. But simply cleaning up the surfaces the ground wires are fastened to and replacing your OEM wires would probibly help just as much if not more.

I understand you're looking for more than one persons opinion here, which makes a lot of sense. But there has been several people chiming in with the same answer.
Yes Kai is chiming in a lot, but it's because he's right, and this has been discussed to death more than once.


89civicSiR: With a relocated battery, the cap would help the voltage spikes caused when you switch on your lights or wipers. And mainly help with the initial demands of the starter. Thsi is due to hte additional resistance in the circuit due to the longer power wire.
But a standard audio cap would work the same(or better) and would probibly cost 1/2-1/4 as much as this kit.
And the ground wires would still do nothing compared to replacing&cleaning your OEM grounds.
