2007 E90/N54: Which coils and plugs?

TenOx · 10-20-2021, 03:45 PM

Just did brake pads on all four wheels + fluid flush, and reset the brake-fluid warning light.

Now the SES light is on and she's idling a bit rough. With nearly 90k miles on the clock, so I'd like to do as many tuneup items as I can and see if that will sort it. First, I would like to replace coils and spark plugs. The car is stock. Looking for good choice for plugs and coils, and a recommended source.

Suggestions of what else to check would be appreciated.

Thanks.

I would just order the kit from FCPEuro. I finished replacing my plugs and coils on my N55 last week. I believe the coils were Delphi and plugs were Bosch. I’m not sure if the N54/N55 coils/plugs are the same but FCPEuro won’t steer you wrong. It’s a super simple DIY too.

For ignition coil, I've used Bosch 0221504470 with great success.
