Installed the coil packs from the Audi RS3 today. Some have had decent results with them reducing knock and smoothing idle. Part# 06H-905-110-G. The coil packs I am replacing are: Part# 06K-905-110-K. These coil packs are known to have some problems so I wasn’t too sad to replace them.
Installation is simple and you can use the spark plug guide I wrote here on how to do it: https://www.carworklog.com/2017/03/04/guide-how-to-replace-spark-plugs-on-the-ea888-gen3/
As others said on the forums idle was noticeably smoother. I am running the same spark plugs for this test, the Buru RS7 spark plugs. I have a pair of NGK RS7 plugs ready to go but didnt want to change too many things at once.
The other thing I noticed was how smooth and strong acceleration was. I dont have stats to back it up but it sure does feel a lot better. This is all in prep for getting my next Cobb protune done.
I picked up the coils and plugs as a kit from HS Tuning: https://www.hstuning.com/product_info.php?cPath=24_32&products_id=5715
