Ignition coil Bosch or OEM Audi

I’ve ran Bosche in all my M3’s with great success.

I’ve used Bosch without issue as well.

I've a 09 E89 3.0 and went with the Bosch coils about 2 years & 20k miles ago and haven't had any problems yet

I have a Y2014 2.5L JSW. I went to the BOSCH (a lot cheaper) route and 10K miles later, no problems.

The Audi r8 ones are good tho, for a tuned vw

I used R8 performance coils in my mk6 golf R. Have been excellent.

I work at a BMW specific shop and all we run are the Bosch coils. I personally have them in my E46 M3 and 325ix. We've sold 1000s of them with zero issues.

Went back to old Bosch coil (which was not bad before) and no change.

Few months ago I got all 6 OBD1 Bosch coil packs and it changed nothing for me other than a slightly smoother top end, I still have a slight misfire at idle.

I replaced all 4 in my tuned stage 2 q3 2013 to red bosch coils. 1 of the red ones died last year.
