Background:
During the process of swapping parts for testing, one thing I keep in mind is ways to make the process easier. A coil ground kit (CGK) replaces the double-nut design of the factory bolts that hold the coils in place, simplifying the removal and installation process. It also replaces the pesky oval bolts with round bolts.
I’ve never observed issues with my GTI ignition system, so the potential for improved grounding from the CGK has been a non-factor in my decision to purchase one.

Options:
When I first sought out a CGK, the two options I found were from SC Skunkwerks and EQT. The SC Skunkwerks kit was less than half the cost of the EQT kit, at $65 versus $140. Given that the kit consists of four wires and four bolts, it’s not exactly inexpensive, even at $65, making $140 seem exorbitant for what you’re getting.
I’ve used the SC Skunkwerks kit for about two years as of the date of this post and have not had any problems with it.
When an acquaintance asked me to help them with some preventative maintenance on their GTI, I learned that another CGK option was available from a seller on eBay who is near me in Orlando – HKA Performance.
At $55, the HKA Performance CGK is slightly less expensive than SC Skunkwerks and offers significant savings compared to EQT.

Install:
Undertaking my third install of one of these kits, things went smoothly.

The HKA Performance kit has been working well for this person for about three months now.

Conclusions:
I acquired a Coil Ground Kit (CGK) for my Mk7 GTI to simplify the process of removing the coils. I have found the elimination of the double nut design of the stock bolts to be beneficial, and the round bolts used in the CGK also ease the process of removing and installing the bolts.
I’ve purchased kits from SC Skunkwerks and HKA Performance, and I’ve been satisfied with each in terms of both quality and cost.
