How To Verify Your Coil Pack Connector
In order to confirm fitment and ensure that you order the correct version of our Coil Grounding Kit (CGK) you must disconnect your ignition coil connector from your coil pack. On the under side of the connector you will see a string of Characters below the VW/Audi stamped logos. The first three characters will be either 4D0 or 8K0. This will tell you which version of the kit you need for your vehicle. See image for further clarification.
The Problem With Factory Coil Grounds
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 EQT Coil Grounding 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.
Assembled In California
Each kit is assembled in house by our expert production staff at our location in California.
The EQT Coil Grounding Kit (CGK) is constructed of only the highest quality components.
- Proper automotive grade TXL wire that meets SAE J1128 specifications.
- Protective flame-retardant heat shrink with high heat and chemical resistance meeting M23053 specifications covering the entirety of the harness.
- EQT branding on the harness to ensure authenticity and guarantee of quality product.
Coil Grounding 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
- 4 washers - Some customers have had problems with bolts not fully bottoming out during installation due to damaged threads or debris so we are including washers in the event you have this problem. Most customers will not need to use washers.
- Terminated into OEM 3.5 Series terminals with an amp seal which replaces the factory grounding wire entirely.
