Coil Grounding Wire Kit for EA888 Gen3 engines used in A3, S3, Mk7, Mk7.5, Mk8, and R models with 2.0T and 1.8T engines.Replaces starting with 4D0.The factory cam cover is made of soft aluminum which can strip easily, compromising the ignition coil's ground connection.Worn threads may lead to reduced spark energy or unnecessary knock retard.This upgraded grounding wire ensures a and consistent electrical ground, improving ignition performance and eliminating issues related to thread damage.Constructed with Teflon-insulated, silver-plated copper wire for stable conductivity and under temperature conditions.Removes the need for the factory double nut setup, providing enhanced grounding stability.When replacing the factory wire, a pin removal tool is required for safe connector disassembly.For Mk7, Mk7.5, and Mk8 models, connect to the grounding lug behind the passenger-side headlight.On A3 and S3 models, use the grounding point near the passenger-side frame behind the fender, or alternatively, the M6 threaded hole on the engine mount if access is limited.For A3/S3 8Y models, routing to the driver's side chassis grounding point near the rear is an option.
