I was kind of skeptical on these systems also but I read a pretty good article in the new April '03 Turbo magazine on page 86 where they tested some ground kits on a dyno on various cars. the results are pretty intersting. You guys should read this article, you might gain some enlightenment. They explain differences if each kit (copper content of wires with some kits) and what the benefits can be.

I'm having a hard time trying to understand why the aluminum air intake plenum has to be grounded in three locations.

One would think that the entire engine assembly, block, heads, intake, timing case, would be treated as an integral unit electrically. Looking at the engine from the front of the car my G35S has a braided strap from the right side of the block to the body, a cable from the front of the timing case to the body and a cable from the rear of the timing case to the body. The battery is grounded to the body.

I can understand running a cable from the engine directly to the battery in parallel with the stock grounding system but not the other cables. The alternator would seem to be a source of RF but it is not included in the grounding system. Also, why are the block and transmission not included in the grounding system?

Is there an electrical or control systems engineer in the group who can provide some insight? TIA.

thanks Dan, maybe that would be a good idea to run a cable to the alternator too.

Anyone know the difference between the single cable sets vs. the sets that have the split cables?
