The EQT Coil Grounding Kit (CGK) is designed and engineered to provide a simple solution for a common problem on the MQB EA888.3 Platform.

The Problem:
The factory cam cover is soft aluminum and is prone to stripping regardless of how careful you are when removing or installing the OE stud. Your ignition coil uses this stud to ground the coil circuit and any amount of damage can occur in a weak ground which may induce unnecessary knock retard or reduced spark energy, even if the threads are only mildly damaged.

The bolt is often removed and installed when servicing the ignition system or performing engine testing. Such as replacing spark plugs, ignition coils, performing compression, or a leak down test, etc.

VWAG in their infinite wisdom also uses oval bolts which exacerbates the problem the more times they're removed and installed. 

The Solution:
By isolating the ignition coil ground to its own circuit and grounding it to the chassis, the need to remove the top nut is no longer necessary and the risk of having a weak, loose, or damaged ground is removed.

While you still need to remove the stud in order to remove the ignition coils, you don't need to "double nut" it anymore in order to ground the circuit -- preventing the chance of a weak circuit.

Construction

This Coil Grounding Kit (CGK) is constructed of only the highest quality proprietary components. 

Assembly Quality:
Each kit is assembled by hand in the USA to ensure the highest level of quality control.

Kit Contents
  • Installation Instructions with High-Resolution images and clear steps
  • 1 x Precision Made Coil Grounding Harness with OEM Terminals for direct installation to your factory coil pack connector
  • 4 new flanged Bolts to replace the factory ones, and reduce likelihood of stripping them with the removal process.
  • De-pinning Tool

Terminated into OEM 3.5 Series terminals with an amp seal which replaces the factory grounding wire entirely. **This installation method requires pinning and depinning of the factory connector and is covered in detail within the installation instructions.

 

Fitment

  • GTI/GTI & Golf R - Utilize the Grounding Lug behind the passenger Headlight
  • A3/S3 - The grounding lug is located behind the passenger headlight on the frame, closest to the fender. You may also utilize the M6 threaded hole on the engine mount if the grounding lug is not easily accessible 
  • 8Y A3/S3 - You may want to route the grounding lug to the driver side and utilize the OE chassis grounding location near the rear of the battery.
  • Mk8 - Fitment confirmed. Same as Mk7/Mk7.5

Does this kit remedy the loose bolt problem?

The EQT Coil Grounding Kit removes the dependency on the factory coil securement hardware to ground the ignition circuit.

By no longer requiring the factory fastener it does allow you to utilize a true round m6x.10 metric fastener which has a much lower chance of causing damage to the threads.

It does not remedy any existing damage to the cam cover threads where the M6x1.0 metric fastener threads into, that is on the installer to resolve by means of a Helicoil or Timecert.

Preventative maintenance is worth it

I've seen people breaking their coil grounds all over the internet so I figured I'd nab this kit so i don't have to worry about my grounds getting weathered and cracked since I run a vented hood. Product is well made and even came with an eqt badge which honestly I was more excited for than the kit. Install is super easy so long as you have a de-pin kit. Only thing that's upsetting is right after I installed this kit they came out with the set that included coil packs for a little bit more but hey that's on no one but me. Just get the kit already (with coil packs so I can live vicariously through you)

Grounding Kit

Overall a great experience. Due to user error, I installed without disconnecting the battery and my car would light up like a Christmas tree. Did a reinstall and went smoothly. Way better than OEM grounding kit. Highly recommend.
