Spark Plug Change Part/Tool List

I'm putting together a list of everything I will need to do this job, assuming using the Bosch plugs. Different options show below.

Updated in red font what i ordered 4/14/2020

1. Plugs
FCP Euro, Bosch - https://www.fcpeuro.com/products/bmw...037580#fitment
FCP Euro, BMW Branded (Bosch) - https://www.fcpeuro.com/products/bmw...ug-12120037582
Any reason to pay more for the BMW ones?
ECS, Bosch (these still show the "S" on the end of the Part #) - https://www.ecstuning.com/b-bosch-pa...20037582~6bos/
Kies Recommended - https://www.amazon.com/dp/B07GL8S81W...sports_dp_vv_d

2. Thin walled socket 14mm spark plug sucket
FCP (not magnetic but has a rubber ring for plug) - https://www.fcpeuro.com/products/12-...mm#description
FCP (OEM BMW tool, expensive) - https://www.fcpeuro.com/products/bmw...et-83300495560
ECS (says magnetic) - https://www.ecstuning.com/b-schwaben.../001247sch01a/
Turner (says magnetic) - https://www.turnermotorsport.com/p-3...cket-38-drive/
Kies Recommended (no magnet but has clips) - https://www.amazon.com/dp/B076YLTTZ5...sports_dp_vv_d

3. Torque Wrench - make sure it goes low enough, 23nm +/- 3nm (18 +/- 2 ft lbs)
After an unnecessary amount i research, i went with these:
Torque Wrench - https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
Device to verify, because i am paranoid and like data - https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Note, watch this video regarding the impact of Ujoints on torque specs:


4. 10mm socket, E-18 Torx (external) socket. 3/8 drive, extension, other basic tools. Might need a Ujoin or swivel to use a 3/8 in extension on the plug socket due to the angle of the spark plug hole.
I dont have external torx so i am probably going to order one of these sets:

Ordered these - https://www.amazon.com/Neiko-04300A-...552218&sr=8-11

5. "One time use" bolts, replace if you want to or feel necessary.
What is the part # for these? Is it 07147270121 or 31106854219? https://www.realoem.com/bmw/enUS/sho...diagId=51_8381
I ordered a few of both. They are used in multiple places so i figured it doesnt hurt to have them.
I think its the 07# based on another thread, but realOEM is confusing - https://www.fcpeuro.com/products/bmw...20-07147270121
Here is the other one - https://www.fcpeuro.com/products/bmw...-9-31106854219


Other potential spare parts:
When you lift the coils out, the flip up pull will likely break/split, so order 2-3 of these extras. You don't need to buy a new coil!! You can reinstall a broken piece without a problem. Just a pain the next time you need to do the job.
