I've never actually installed them. I was going to go with the Eldor since there isn't as much feedback on them and I wanted to see for myself. Have you tried both the 328 and the 571?

 

[Milan]

I've tried the 571 and Eldor and noticed no difference. Ironically there was a situation where my Bosch coils solved a miss on my Delphi.

How many miles were on the delphi?

How many miles were on the delphi?

Not very many, I'll go with 5k or so...

 

[ysjeon1698]

anyone know where I can get delphi 571 for cheap? Amazon is too expensive... and dont really want to pay $220 for 6...

Went with Delphi before and now on Eldor coils.
No complaints for NGK 95770's gapped at 0.18" on 100% E85.
Anyone recommend something else that runs better?

 

[mkster08]

I have the NGK coils I found a while back coming in next week.. U5055 is the part number if anyone wants to try them out too.. I got them for $25 a piece. NGK makes some good stuff so we'll see

I can't remember, but what is the suggested life for spark plugs running say stage 2 mhd? thanks in advance

Suggested? I think suggested is like 20k miles but, you could probably push a 25k and have no issues.

Is anyone going to update this thread with the new smart coils? And recommended plugs gap?

I've added brief mention of both products. I'll refrain from posting recommended gaps until they provide them.

Okay its gotten to that point where the influx of newcomers to the platform is rapidly rising and there are several common questions that get asked repeatedly and this will focus on a few maintenance items. For the sanity of the veterans to the platform, it is nice to have threads like these to reference. This post will hopefully answer some of those questions and I will update this as much as possible as information evolves. Lets get to it:

Spark Plugs (Thanks to @CKI@motiv for this info)

BOSCH ZGR6STE2	Identical to OE and cheaper
NGK 95770 (ILZKBR7B8DG)	1 Step Colder (FBO+)
Autolite XP 5682	1.5 Steps Colder (FBO+)
NGK 93026 (DILKAR8A8)	2 Steps Colder (700hp+)
NGK 97506 (SILZKBR8D8S)	2 Steps Colder

Injectors
There have been several revisions to the injectors over the years with Index 12 being the most recent at the time of writing and seemingly the most reliable. There are many places to get these injectors for a significant discount over OE sources, which I will leave up to you to locate. It is important for various reason to ensure all six injectors are replaced at the same time with the same type. You can mix and match Index 11 and 12 injectors with the correct coding, however you may experience bank variances.

One additional bit of information is in regards to injectors is an extended warranty for certain build dates. See below if you qualify for reimbursement:




Coils
Anyone purchasing new OE coils should wind up getting the new design with the metal housing from Eldor which seem to be a solid choice. There have been a few performance oriented coils such as the Okada Plasma Direct, however its been said that there are better ways to spend that money. There are also many people running the N55 coils by Delphi.

Eldor #12138657273
Delphi GN10571

Upgraded Coils
There are currently two upgraded coil offerings:

BimmerLife Tuning	Smart Coil
Precision Raceworks	Dumb Coil

Just got a set of NGK 97506 plugs for my 08 bmw 535xi e61 6MT, Car is fbo+ inlets & outlets. My question is to those who using them , if you are using any type of anti-seize lubricant on them before the install? Thanks in advance

unprofessional opinion - I would think that there's no need UNLESS the plugs lasted a long time, and they don't, so..

tighten it to spec and let the crush washer do it's thang

 

[Vbp6us]

Well, it looks like the coil part of the equation has been largely resolved with the advent of PR and Bimmer Life coil kits.

Indeed, currently looking into getting a set for my personal N54. I've been waiting for more feedback over time since they released but, from what I've seen its a solid purchase.

The debate now is which path to choose. PR or BimmerLifeTuning

I did Delphi IIRC and it was the same as OE Bosch
