Ignition coil Bosch or NGK

I have Bosch in my 2015 currently with no issues for 30k miles so far

I’ve ran Bosche in all my M3’s with great success.

Ainda assim, pus bobina NGK e comprei as velas NGK tb (mesmo código da css, só que mais baratas. De 300 por cada uma de Iridium na css com logo da hyundai por 120 na autopeças).

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.

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.

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.

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.
