lang=\"EN-US\" style=\"color: rgb(0, 0, 0);\"\u003eThis kit replaces the 4 individual coil grounding wires on the MQB Platform with a dedicated grounding harness.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan lang=\"EN-US\" style=\"color: rgb(0, 0, 0);\"\u003eWhy Upgrade?\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan lang=\"EN-US\" style=\"color: rgb(0, 0, 0);\"\u003eThe original method for grounding ignition coils on this platform is inherently flawed, relying on providing the necessary contact via bolt thread in the alloy cylinder head. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan lang=\"EN-US\" style=\"color: rgb(0, 0, 0);\"\u003eThe factory bolts use a triangular thread (less overall thread contact) which are intended to provide resistance to backing out, but also require more torque to tighten and increase the risk of stripping the thread.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eNone of this is an issue for a vehicle fresh out of the factory, however when factoring in the removal \/ installation of ignition coils throughout regular servicing, this grounding method will produce significant wear on the threads and overall grounding consistency.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eOur solution is to use a dedicated grounding harness, which provides a shared point for the ignition coils directly to the primary grounding stud in the engine bay.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eThis ensures that your ignition coils will always provide a strong spark under high boost, while also simplifying servicing.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan
