Good stuff

Well made
Clear instructions
Price hard to beat !!

Great product and packaging awful construction

Let me start off by saying it looks great and is packaged great and instructions are really well put together. But all 4 terminals where not crimped on very well and when I went to give it a very light tug to make sure it was seated in the connector the wires pulled out. Once the first one pulled out I checked the rest and they all pulled apart with extremely low effort . They did not seem to be crimped as well as the oem coil pack grounds where.

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.
