I added ground wires to my last car (an Elantra GT) with some good results. I noticed smoother idling and power. With my Elantra, I ran the wires from the battery negative to the coil pack to the intake manifold to the firewall.

What would be the best connection points on a 2010 Forte SX / Auto?

Thanks.

We grounded the brothers throttle body the other day. With a multimeter it was reading about ~3, after the grounding it was zero'd out. A DBW car the TB is always the best place.

But some others include fuel rail, alternator, the block, etc. Any thing really with a residual charge. Use a multimeter and find some.

But don't expect any drastic changes.
