Ignition coil DELPHI or Bremi

Get the Delphi coils, no need to buy genuine BMW.

I just put the latter on my 2000 S, they work well.

There are a lot of parts you can trust aftermarket, but electronics are usually better OEM. Denso and Delphi make a lot of OEM Subaru parts. In this case, I believe Delphi is the OEM manufacturer for coil packs, I would try them.

Delphi. BMW started with Bosch and after misfire issues they switched to Delphi (I think in 2011?). Go with Delphi, my old e82 with an n52 had tons of misfires at 40k with Bosch coils and the Delphi’s had no issues.

I had issues with misfires until I replaced the coils with genuine oem. Before that I had all new Delphi 10571 which were not the same and ultimately fixed my misfire issues.

I have OEM Bremi coil pack now. the original Bremi OEM coil went 15+ years and survived 1 OEM cat and 2 magnaflow cats.

I won't install anything but the Delphi coils.

Bosch Delphi eldor they’re all the same you can’t really say one is better than the other. Some go bad early that’s just what it is. I personally went with Delphi (they’re quite a bit cheaper on eBay). But the lifetime return/replacement from fcp is pretty enticing.

They’re made by Delphi but they are different internally than the Delphi gn10571 or whatever they are, in the aftermarket. I had misfire issues and strange electrical feedback with Delphi aftermarket.

Bremi ignition coils would crap-out
