Down to Earth

Resistance is futile! By resistance, I mean electrical resistance involving car electrical system. Good electrical performance requires a grounding system that's prepared to take a lot of current with minimal resistance. Your spark plugs, lights, fans, ICE, air conditioner, too-fast-too-furious-look-a-like undercarriage neons and so on all benefit from good electrical cabling. They all share a common ground, however, these ground connections rusted or come loose over time, the amount of conductive material decreases. This leads to resistance.

A quick option to solve this problem is by changing all the factory earth cable or the cheaper and popular choice; by adding additional ground cable, known as ground wire kit or earth wire kit. Beside multiple names it has, the earth wire kit serve only one purpose; get your electric current grounded. How well this tiny cables are going to help the thicker factory cables? Was the material used is superior than the factory's? I seriously doubt this bunch of wires with some broken english on the packaging with misspelled word will do much different. But, since it was on sale, I bought it.

I put the additional wire on cover rocker, throttle body, alternator, air cond compressor (? - got an extra wire, I just mounted there) and ended at the negative battery terminal.

Did I noticed any less dimming headlights? No.

Better fuel consumption? No.

Increased power and better low end torque? Are you kiddin' me?

But I've experienced a smoother and subtler cam engagement though. Radio reception seems to be better by a lil margin, apart from that, this cables serve more as cosmetic item rather than functionality.

In my opinion, earthing kits do work to some extent, but only with older cars where earth has deteriorated badly; such as a very old half-cut engine from junkyard. Most of the time the engine bay is exposed to rain and those ageing cables couldn't perform like when they were new.
