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.
Without the need for a stud on top of the bolt, you can easily replace your existing hardware with round M6x1.0 thread pitch bolts instead of the OE oval hardware.
OE Hardware is N91229201 and measures 45mm UHL (Under Head Length) and 12mm OHL (Over Head Length). To replace this stud with an appropriate size bolt you would want M6x1.0 x 45mm. You may also use a 40mm length if you chose. There is sufficient thread engagement to hold the coils securely

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

Kit Differences
Standard Kit:
Includes M6 stainless hardware to attach the harness to your existing OE coil pack ground wires. **This is the easiest method of installation and is easily hidden under the factory plastic wire loom and engine over
Pro-Kit:
Pro-Kit: Does NOT include M6 Hardware as a method of attachment. Instead, the CGK is 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.
Damaged Connector?
The Pro-Kit also allows you the option to replace any damaged OE coil pack connectors with new factory connectors (OEM PN: 4D0 971 994) which is also fairly common on this engine. Detailed instructions are provided with the pin assignment and wire colors to aid in this process.
Fitment
All MQB EA888.3 Powered vehicles and EA888.4 8Y S3 with 4D0 971 994 coil pack connector. Verify which plug your vehicle has before purchasing.

Additionally, on each product page, we have a tab for fitment information. By clicking on "Fitment", you can scroll and verify the part you are about to add to your cart indeed fits.
Furthermore, if you have a vehicle added to our vehicle selector and you are viewing a product page, you'll see fitment information below the "add to cart" button. If an item fits your car it will display "This Part Fits Your: Selected Vehicule". If an item does not fit your vehicle a message will display "This Part Does Not Fit".
A “Core Charge” is similar to the deposit you might pay for a can or bottle of soda. In many states, to promote recycling, you are charged a deposit when you purchase a can of soda and you receive your deposit back when you return the empty can. Many automotive parts have Core Charges that work the same way as a soda can deposit. The most common car parts that include a core charge are alternators, calipers, steering racks, and fuel injectors.
"MAP" pricing, or Minimum Advertised Pricing, means that the vendor set a minimum retail price that we're not allowed to violate. MAP items cannot be discounted because the decrease in price would violate that threshold.
