Owner reviews for ignition coil

Stock Bremi/bosch are the way to go.

I got the Denso from Amazon it wasn’t cheap but you don’t want misfires with after market cause the car will idle and drive like shit.

NGK. Coils aren’t something worth saving a couple bucks over picking a worse part

Ngk has been much better in my experience

I've had success with NGK coils via Rock Auto on multiple vehicles.

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

NGK plugs and Delphi coils. Do not get Bosch

Bremi had premature failures in the first few years of the e46 and were replaced as OEM by Bosch.

Avoid Amazon if possible. I got fake NGK ignition coils once. I wouldn\u2019t order any part that is easily counterfeited off Amazon. Also got crush washers that were supposedly OEM spec, but they were made with the flimsiest piece of shit ever. I could bend them between my fingers.
