Ignition coil Bosch or Bremi

I ended up going with Bosch and haven’t had any issues.

Just stuck a load of Bosch in mine, worked a treat, xHP throttle blip downshifts were sometimes jerky and causing transmission faults but now they’re as smooth as butt’uh.

Around 2 months ago, one of the starting coils failed. I checked here and some said that the stock "Delphi" coils are known for failing. So i changed all of them for "Bosch" coils.

get the Bosch brand their the same as OEM trust me I know don’t get any other brand even though their going to be cheaper get the Bosch. Besides honestly most of the ignition coils is Bosch companies just throw their name on it to charge more

Get a Bosch and skip the brand logo. Same part and available…aaand cheaper. Same issue for me c63s.

Bosch working great for a few years now, cheap as dirt on rockauto

I bought the Bosch 4 yr and 10k miles ago and haven't had issues.

I assumed it was bad and while it was sad to get rid of the OE Bosch, Autozone had a C831 coil that I was able to pick up. I think the boot was slightly too small but I’m 90% sure it’s making contact but I am still not getting it to arc.

I believe Delphi is what people switched over to because the Bosch coils were failing.

Bremi ignition coils would crap-out
