That said, if you are going to do it, solder the ends, and make the lengths as short as possible of whatever size wire you use...

This kit goes to two places on the intake, one on the intercooler, and the right strut tower. The theory is to get the grounds as close to critical sensors as possible I guess. I'm sure others go elsewhere...

Sorry, no perfect answers from me at least...

I didn't get a kit or anything, but I've heard some *rumors* about better grouding = a better longevity(sp?) of the internals (nutral oil or something). Plus, it wouldn't look bad as a somewhat "engine dressup" kit. I was thinking about just replacing the stock wires with some 4-8 gauge wire from circuit city or any other audio place. I believe I can make a kit for under $20. I ask you guys because I've seen some of your cars with a grounding kit and I heard its popular with WRX drivers.
