Boost your MQB EA888.3 engine's performance with this high-quality coil grounding harness kit. It swaps out the factory coil grounds for a shorter ground path, improving conductivity and spark performance.

Kit includes:
- 8K0 or 4D0 Coil Ground Harness
- 4x Replacement hex bolts
- Terminal removal kit
***Part number will need to be verified before ordering. Part Number will either begin with a 4D0 or and 8K0, and can be identified by comparing your connector to those pictured in our reference picture. 8K0 also fits Euro ignition coil connector 8K0971994A with red tab.
When installing - before attempting to depin the wires from the connectors. Make sure to remove the purple locking tab shown below:
After removing the OEM wire and then installing the coil ground kit pin - reinstall the locking tab.
