Just a question about these supposedly high performance Grounding or Earthing kits for vehicles I have seen advertised in different places.

Supposedly these are the advantages:
·Improved Engine Torque
·Better Gas Mileage - Fuel Economy
·Engine Power - Response
·Engine Kick Over (what, your engine doesn't kick over already?)
·Audio Performance

AFAIK all they are is a heavier gauge wire to replace OE cables (but look pretty).

What are the advantages, if any, and will any thicker gauge do the same job anyway?

i did a diy setup for my astina - only thing i noticed was slightly smoother idle. nothing else.

they usually are in addition to the stock hos earth wires

dont waste money on a "kit"

upgrade your ground strap to some 4GA. I added a second one that bolts to the chassis rail under the battery also. cost me $10 for an auto elec to make the leads up for me once i measured it
all.
the factory ground strap is a joke.. it is way too small.
