Ignition coil Bosch or Bremi

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

Ive had mine misfire all of a sudden, whole car shook, CEL lit up, said code "cylinder 1 misfires" sometimes it ran normal but then rough again. If i gave more than 1/2 throttle it shook even more and it had no power at all. When i checked the coils on mine they were original "BREMI" manufactured and even the date from back in the day was on the bremi coils. They now held up 230000 kilometers since when the car rolled off the factory, thats more than enough service

I’ve never had an issue with my Bremi coils. Just replaced the suppression tubes. M50/M52 coils very rarely fail. Just the tubes.

I run the bremis on my drift car work great

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.

I was told once by a distributor of many brands including Motorcraft that Bosch made the Triton coils. Our group sold thousands of them, with very little trouble.

All 4 coils (they´re now Bosch red color)

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 had all new Bosch coils installed on my e46 M3 about 30k miles ago. They worked fine, until one day the car went into limp mode due to bad coil / misfire.
