STILLEN : STILLEN Grounding Kit

"These grounding kits will also improve the shifting on automatic transmission vehicles, and in most cases noticeably improve shift times and reduce lag."

Anyone here with an AT drop these in and actually see a difference, good or bad, with shifting? Or even those with a MT did you see any difference with these installed? $90 seems step for something you could easily make yourself.

I can't imagine that would possibly improve shift times, or do much of anything at all. Looks to a product along the same lines as magnets you put on your fuel lines to "align the molecules" in your fuel for more power.

I have a red grounding kit....but only for looks. I never noticed any advantages....it just goes well with my red Nismo engine cover.

I would think they would only improve things if the stock groundings are not big enough to carry all the electrical load and then that could cause some latency in things.

So I made/had 2gauge wires on my last car (automatic, w/ a shift kit in it). I didn't notice any difference. On the 370z, once again I didn't notice a difference. I drove it about 2.5hrs today post install, and car acts just normal. With that said, I didn't expect to feel a difference. I wouldn't say these are cosmetic (although placebo is a hell of a drug

), but more of a 'feel a little safer now that there is more leeway with the grounds'. You may argue it gains 1-2HP, but on a car w/ 300+, you'd never notice that anyways, so whats the point in arguing it.

As for grounding the throttle bodies... I just did what the instructions said, but you do make a good point. On every other ground point, your increasing the size of the wire, but there is no ground on the throttle body itself. So, you make a good valid point, I didn't even think about it when putting them on. It could be argued that the entire engine is conducive so your just strengthening the ground of the motor in general. I'm not sure if there is a good metal link from the throttle body to the rest of the motor though, and it wouldn't be worth the time to get into anyways.

I can't tell from 2theextreme's pictures, but his may not even go on his throttle body. You can also note that some of his end points are in different locations. This isn't exactly a very specific science like say a turbo is

grounding kits really only see their biggest (or any) gains on older efi cars. if you have a 91 civic si in your driveway go ahead and buy that grounding kit you saw in a super street, because it is basically a secondary ground system to replace your decades old and corroded factory grounds. on older cars they take a little bit of noise out of the sensor signals and improve spark that is where you get benefits from. if you have a good factory harness with clean connectors, and good signal it is a waste of 100-200 bucks

^^^ Bingo.

And the fuel magnets do nothing... well, they might cause some ECU interference

Also, speaking of magnets -- the folks that use the magnets on the oil filters -- isn't our block aluminum? Am I missing something?

the alluminum block kinda makes it seem funny but you have to remember that our timing case is flushed with engine oil so the materail wearing off of the chains and sprockets will get flushed into the pain. and when pieces of dirt or casting sand manage to work their way into a bearing they can rub material off of the crank and cams, also there is minute wear of the lifters and lifter to rocker cam things(whatever you want to call that on vvel i'm to lazy to look it up right now). also the oil pump wears down over time as well so there is iron wear in the engine to what degree who knows but thats where the iron count on a UOA comes from molecular iron particles floating around in the oil(which are often times much smaller than the pores in the filter media and are basically harmless but serve as a good wear indicator).

^^^ Hmm... Okay, these are valid points... does anyone actually catch anything tho'?

I have the grounding kit and I haven't noticed any changes in shifts or anything for that matter. I was told they would benefit the most with aftermarkets radios, and other electrical items. It does dress up the engine bay quite nicely tho

espcially with the red wires
