E90 N55 Ignition coils suggestions?

deadlyhate · 04-06-2020, 03:10 PM

Hello,

Almost 1 year ago I decided to tune the car (not by myself and not JB4/MHD). It is an E90 N55 LCI 335i.
As a precondition I decided to change the original coils (they are Delphi - no clue if they are the original or etc) to NGK U5055.
For the last 12k kilometers I had no problem until yesterday. I got misfire in cylinder 2. So removed the 2nd cylinder NGK coil and plugged in the original one (which I have saved ofc) and the car started working normally again - no errors, etc.
So I guess the coil was bad. At this moment I am thinking of buying new set of coils (I am not sure If the rest of the NGK coils will follow the fate of the 2nd one) but I am not sure which brand/model to go for.
The car is currently at 370hp (590Nm) and I am not really planning to go much higher (at least for now), since I use it for a daily drive and I enjoy it like this. I do not know if the coil just could not handle the tune?
The car has BMS intake, VRSF 7" Intercooler and custom downpipes & exhaust system.

So my questions are - what are you currently running? Are you happy with the results? Any suggestions related to brand? Or any suggestions at all?

Note: I am from Europe, sooo - if the suggestions can be found on this continent it would be a big plus

I have the same car and am running a fresh OEM setup with no problems but plan to do Precision Raceworks next, tons of great reviews on here.

Precision coils are overkill unless you have an upgraded turbo running higher boost.

I have had my PR coils on my car for a year now and it been absolutely worth it. Not a single problem!

2011 335i xdrive, ARM 5" inter cooler, BMS intake, VRSF 3.5" downpipe, ARM chargepipe,PE mod, PR coil packs, MHD stage 2+ and xhp stage 3.

What I wonder about is according to what I found the S55 has the same coils, but people get out a lot more power. Why?
