034Motorsport C4 Audi UrS4/UrS6 & S2/RS2 I5 20VT AAN/ABY/ADU Coil Pack Update Harness for 2.0T FSI Coils

This plug-in harness lets AAN-engined C4 Audi S4 and S6 (UrS4 and UrS6) models and ABY or ADU-engined Audi S2 and RS2 models run updated 2.0T FSI ignition coils with built-in power output stages. 034Motorsport explains that the factory coil output stages on these I5 20VT engines are notoriously failure-prone, and intermittent or premature failure shows up as hesitation or a miss under acceleration. The harness uses OEM-quality connectors and automotive-grade wiring, installs in minutes, is fully reversible and comes with instructions for modifying the OEM 2.0T FSI coils to fit. Coils are sold separately, with genuine 07K 905 715F coils recommended and 1.8T coils not recommended, and the brand has tested the setup to around 275hp but does not position it as a performance upgrade.
