I agree it shouldn’t change anything. I didn’t expect much also except it did…Changing just the ground wire, even to a thicker gauge, should not result in anything…unless the original wire is of insufficient gauge. The new wire looks nicer, and not having the conductors exposed to air/moisture is a good thing. I can understand buying it on just those merits.
How do you prove a smoother transmission except from from your own driving experience?Bullshit. Show me proof.
You can read this https://forums.nicoclub.com/what-is...ow-does-it-benefit-someone-s-car-t419658.htmlHow does the gauge of a grounding wire affect the smoothness of a transmission? What's the logical thought process?
It’s a manual transmission - how does an electrical change make it shift more smoothly? The link to the nicoclub forum appears to be for G35/37 - which I believe was available with both a manual and automatic transmission?
