NC MX-5 Miata Earthing/ Grounding Kit Install & Battery Maintenance

Do earthing/ grounding kits really work? Do they improve your spark efficiency? Do they make your audio sound better? Do they increase power and smooth out idling?
The answer to all the above is a big fat "NO". But they can look cool!
In this NC MX-5 Miata DIY vlog, I did the following:
✅ Replaced battery.
✅ Replaced battery terminals.
✅ Replaced factory ground wires with fancy looking aftermarket ones.
✅ Installed some additional fancy looking aftermarket ground wires.
✅ Did some rust/corrosion prevention on my brand new battery.
All the tools and supplies I used were bought off Amazon and you'll find a full list at this link:
