Assembly Quality:
Each kit is assembled by hand in the USA to ensure the highest level of quality control.- 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 Genuine VW/Audi Ignition Coilpacks
- 4 new flanged Bolts to replace the factory ones, and reduce likelihood of stripping them with the removal process.
Direct Ignition Coil
Direct ignition coils are located directly over the top of the spark plug. In this ignition setup there is one ignition coil per spark plug and there are no spark plug wires. This ignition setup is often referred to as a coil on plug ignition system.
Coil on plug or direct ignition systems are pretty much used on all modern cars due to packaging, performance, emissions, and maintenance reasons. This ignition system is essentially maintenance free with the exception of spark plug replacements and the occasional coil replacement when compared to a traditional ignition system.
Direct Ignition Coil Failure Symptoms
- Reduced fuel efficiency
- Reduced power output
- Misfires
About Genuine VW Audi
The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VAG to build your car are available as replacement parts under the “Genuine VAG” brand. Manufactured under the direction of VAG, expect excellent quality and a premium price since these parts are available exclusively through the VAG Dealership network.
You may not realize this, but the parts that make up your VAG are not necessarily manufactured by VAG. No cause for concern, as VAG designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VAG for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine VAG parts box and find an OEM branded part inside, simply with the addition of a VAG logo.
Coil Grounding Kit
Verify your coil pack connector part number for fitment prior to purchase - See the fitment tab below
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.
Customers who fail to verify their coil pack connector and purchase the incorrect unit will not be eligible for refunds/returns.
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 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.
CGK 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.

- 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.
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?
Our 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/EA888.4 Powered vehicles with 4D0 971 994 coil pack connectors will require the CGK Pro 4D0. For all others see below for 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
- Vehicles with With connector 8K0 971 994 you require the Pro 8K0 Kit and will not work with the 4D0 connector.

Notes
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.
