Ignition coil Bosch or BERU

I use a BERU ZSE001 Ignition Coil, also in a '72. It's bomb-proof - zero starting issues after a lifetime (3 decades!) of bump-starting.

Only disadvantage is it doesn't like being left in the 'contact' position for long, which is not a problem for me.

Conselho: coloque bobinas originais Beru ou então Magneti Marelli. As demais bobinas pra K4M não são boas de acordo com todos os membros do Clube da Megane que precisaram fazer troca delas!

As per ignition coils, the only ones you should buy for N43/53 engines are Bosch. All the others (Delphi, Febi, HP etc.) are the same Chinese coil sold under different names, same issues as the counterfeit parts.

I'm running Bosch and have been for 45k miles with no issues, even tuned running extra boost which demands more of the ignition coils.

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.

I’ve used Bosch without issue as well.

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.

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