AAN engined UrS4's and UrS6s, as well as ABY/ADU engined Audi S2's and RS2's have notoriously poor coil power output stages endearingly called "POS's". Often intermittent or premature failure will manifest in a hesitation or miss under acceleration. Do away the costly POS and replacement coils with updated VAG coils from the 2.0T FSI with built in power stages.
Fully plug-in harness, all connectors feature OEM quality, automotive grade wiring, literally takes minutes to install and is totally reversible should it ever need to be. Includes instructions to modify OEM 2.0T FSI coils to literally pop right in. Tested for performance compatability up to normal "RS2 power levels" in the 275hp range.
We do not recommend using this kit with 1.8t coils, since some chipsets run too much dwell, causing them to cut out at WOT or fail completely.
We do not recommend this kit as a "performance upgrade" over the stock coils. If you are looking for higher performance and a more powerful spark, please check out our High Output AAN Coil Kit, designed for this purpose.
