What are grounding kits supposed to do and do they improve performance? Thanks, Paul

All electrical circuits consist of a source and a ground. The chassis is the ground for cars and all electrical circuits are tied to it. Engine performance relies on how well electronic components are connected. OEM systems are adequate for the job but use small gauge wiring which over time, tends to deteriorate. Grounding kits are meant to guarantee a clean ground to the battery and a better electrical circuit, letting sensors and electronics operate quicker and without as much resistance or noise. Much like when your speakers have interference and are static sounding, the culprit is usually a bad ground. Good grounds are important but are the kits worth the money? If you’re car or electrical experience still includes handholding, it’s an alternative to DIY but with a crimper and bigger gauge wires, you could reground the wires yourself. I recommend using 4 gauge, high audio grade 1666 strand count, 99.99% oxygen free copper wire for the best conductivity. It doesn’t need to be a shielded wire since it doesn’t carry a signal. Newer engines probably don’t need to be re-grounded as their connections have not likely deteriorated. The world rally championship cars use grounding kits and they typically have more advanced electronics where it is most important to have the least amount of impedance in the circuit for accurate and efficient sensoring.
