Big upgrade over flawed factory coil grounding

I’ve been running a harness from another manufacturer on my car, but this one offering the shortest path to ground seemed like a better solution.

A relative’s GTI wasn’t running perfectly smoothly, and so I figured I’d buy this SC Skunkwerks harness this time around. Bought one for that car and another for a different car in the family just for preventative maintenance.

Installation was very easy, having installed similar harnesses previously, but the included instructions were a nice refresher and provided me with some tips I never would’ve thought to do.

Car runs and idles beautifully smoothly again post-install. Very much satisfied and would buy this exact harness again if the need arose. Just make sure to tidy up the harness and make sure it’s not contacting anything.

Bulletproof design, easy installation, value priced

I couldn't believe the quality of the Coil pack ground kit. It was a super easy installation, fast delivery, and fixed my issue with random misfires codes on my Mk7 Gti. The whole experience was flawless with SC Skunkwerks. Thank you!

Perfect Solution

I got this for my B9 Audi A4 2.0T after doing a spark plug change and having to deal with the unspeakable evil that is the triangular shaped bolts securing the coil packs, as well as the stupid double nut for the original ground wires. This kit gets rid of both of those problems. Very helpful instructions, pretty straightforward job. Took me about 30 minutes to install. Quality is solid as far as I can tell and half the price of the EQT kit.

Nice kit!

Everything from the purchase, shipping, and installation of this kit went smoothly. I didn't have any driveability issues with the stock wiring, so there's been no change with that, but I am happy to be rid of the OEM bolts that were annoying to use.

High quality, good value

I picked the cheapest shipping and the product was delivered faster than I expected.

Product was nicely packaged with a nice set of color printed instructions.

Wiring harness is very solid, should work well to provide a ground path for the coils.
