So, I went to my VW/Audi dealers here in Tampa and purchased the stock RS7 spark plugs and RS3 ignition coils. The exhaust smelled slightly worse at startup after the change, but still went away shortly after startup. The idle was smoother but I attribute that to old stock coils and spark plugs.

The only thing I have are the R8 coils, other than that stock everything. The car drives mint
I got MSD Street Fire coils to replace mine and its been 4 months so far and they're running strong.
I have had good service from both Delphi and Motorcraft. I used to use Bosch, but there are a lot of counterfeit Bosch coils on Ebay.
The Audi bolt-down ones are good. I replaced the push-down coils that had a failure about every year or two with the bolt-downs just a week or so befor VW announced the recall. Zero, zero, zero problems ever since.
I pulled all the coils out and one of them was rusted to shit. As I mentioned, I didn't want to pay $460 to get them from MINI, so the parts store supplied me with Bosch coils and they worked well. I ripped the car through the business district I work in ala Grand Tour; all the stuttering problems, hiccups are gone and the car feels way more powerful than before.

I had my old OE coilpack off, replaced with the new BERU unit. I had everything put back together, started her up, and she was running okay, but still far from perfect.
The new Chinese coil quickly craped out also - but not as dramatically as the old one. I had already ordered a huco coil so when it arrived, I returned the Chinese coil for a full refund. It's all good now
The HUCO coil simply popped and failed while driving off at an intersection, no cracks, no water.....just failed.
