Ignition coil Bosch or HITACHI

my first bmw was a 2007 328i and kept having misfire issues. Tried 6 new coils from autozone, still had misfire issues, returned them and ordered Bosch. Misfire was gone.

Hitachi ignition coils. Got mine off Rockauto for $30 each. I believe they might be OE

Whenever I need a coil, I try to find a Bosch blue first. For whatever reason they’re scarce, but I’ve always had good luck with them.

I also got my OEM coils for free but i do now need to replace mine, and will be going Bosch.

i ended up going with BOSCH 0986221072 ignition coils, no issues with stage 1 tune so far. Put almost 20,00km since installation.

Try 07K905715G BOSCH

Bosch makes a lot of the oem coils, so I wouldn't shy away.

Coils: buy Bosch or Delphi coils. DO NOT BUY THEM OFF OF AMAZON. You would be better off leaving them then replacing them with an aftermarket brand.

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.

But, its Bosch ignition coils had a defect and were being recalled.
