I'd stick to OEM Bosch ignition coils.

Bosch is a multi-billion dollar corporation that manufactures its own auto ignition coils. It does everything from mold the body, mold the coil bobbins, stamp its own metal parts, mold its own rubber parts, wind its own coils, assemble all of the components and test the final assembly with high voltages. This allows them to closely control their manufacturing processes and in turn quality.

Can as good, or a better coil be made by others? Absolutely, as long as that other entity uses equal or superior materials and controls their manufacturing processes. I doubt Bav Auto runs their own factory assembling product. They purchase from a third party manufacturer, and have no direct control over the product they buy.

Names like Bosch, Bremi, AC Delco, Delphi, Champion have been around for years and have developed long standing reputations for quality product. BMW uses Bremi and Bosch interchangeably for their OE component ignition coils.

Maybe in twenty years the Bav Auto labeled coils will be considered the best in the industry, but for today I would stick with a known name like Bosch.

Go with Bosch, or the BMW labeled ones which are same Bosch coils, but tested more rigorously by BMW.

Im using Delphi part# GN10571 no issues car runs much better than when i used Bosch

When I did mine, I read something that said to use Delphi over Bosch.

Bump. Going though this problem now.

Had to drop of my car to the dealer because it was spluttering on the freeway and I had a SES light come on. Wanted to make sure I know what the problem is before throwing parts at the car. They said I need spark plugs and coils. The SA told me to use Delphi because they are upgraded. They do not use Bosh coils any longer. I got 6 of them from Amazon.

Funny thing, the dealer wanted $900 to replace plugs and coils. I told him no thanks. I already have plugs in my toolbox drawer. All I needed to get was coils. I am going to replace them this weekend,.

good decision in doing this yourself :thumbup:

Its such an easy DIY - still can't understand Dealer ready to charge so much (including free AC, coffee, fancy showroom etc..)

maxxym 07-22-2016 11:41 AM

Yeah, it's crazy. It took me about an hour to do them on my e39 when I had it. I already have the plugs. Just been lazy lol.

I am going to replace all coils while I am at it. I just hope these Delphi ones will fit. I am reading mixed results.

Reefin' Dude 07-22-2016 01:19 PM

don't you need to program the ECU for the new new ID's on the coils? i thought it was not as simple as just swapping out the coils like in the e39.

etnav382 07-22-2016 02:08 PM

I have NEVER heard of having to reprogram the ecu of any car when replacing coils.

techrunner 07-22-2016 02:17 PM

its not required...just swap...one of my coils was causing misfire and i just replaced that 1 coil and the engine is running as smooth as before...i used Bosch replacement coil ~$30 on amazon..but take care to check the exact part numbers..i had to return once because i had ordered a wrong part..

Reefin' Dude 07-22-2016 02:25 PM

sorry, it is not the coils. it is the injectors that need the ECU reprogrammed when they are replaced.

01 Ignition coil DELPHI (6) 12138616153


when I first got my e60 they had old Bosch coils, replaced them with part number above and car been running smoothly ever since... (never had a problem either before or after but I replaced them anyway plus this is what realoem says to use)

maxxym 07-26-2016 12:09 PM

Bump.

Replaced all coils and installed new spark plugs. Car drives AWESOME now. So smooth.

I don't get how they come up with a $898 figure on this job. This is with replacing only one coil! It took me couple hours to complete it and this is considering that I messed up and started to put back cabin filters before putting engine cover back on lol, so I had to take it apart again.

Easy job!

awesome !! I will have to do this sometime soon as well..what was your car mileage? BMW says replace plugs at 100k..

maxxym 07-27-2016 06:06 AM

techrunner, I have 106k miles.

I used instructions from Pelican website how to remove the cover. That actually was the most time consuming part. After that, removing coils and plugs was a breeze. They were little tight in there but I have a socket with a rubber piece in it that helped to lift plugs out.

I noticed considerable improvement in acceleration and just in general, the car runs very smooth and accelerates smooth.

Knock on wood, so far, I had nothing major happen with my car. I have to say, this is the best car I have ever owned. All I have is a maintenance costs.
