Or maybe #2 gauge? Not sure what is on the S2000. I used an aftermarket terminal on my 2007 Element that clamped down onto the wire. Like the AC Delco ones in the first link. They adjust to different sizes and arrangements of the wire ends. Think I'll get #2 & #4 gauge positive terminal ends. Those are the ones that always seems to corrode, first.

Good luck!

 

thank you! i'll end up getting both as well.

 

Do you have a battery tie down?

 

What gauge wire did the positive side end up being? did the #2 work out well?
