Hey, all.
So after the 'uncertain' results of the grounding mod I did to my 02 WRX, I've been doing some research on the topic of grounding.
I see various kits available (on eBay, for example), which appear to consist of a 'hub', which mounts to the negative battery terminal, and a bunch of leads that go to various locations - engine mount, headlamp, etc.
an example is Ebay item # 150026923746.
The ads basically suggests that these things will cure all ills, and even make toast for you.
I did read an independent review on one of these kits, used on an STI. The reviewer did not claim to notice any improvement in power or smoothness in acceleration - but the review was very specific to say that this change, and this change alone, resulted in significantly better gas mileage.
I'm still not convinced that this is anything but nicely presented voodoo, but am curious if anyone out there has invested in (or created) a kit similar to this and gotten positive results.
It's been about 5 days since my 'bodged' ground mod (negative terminal to passenger side strut bolt and negative terminal to passenger side intake manifold), and it still feels pretty good.
Thanks!!
