I heard
1) I should ONLY use MB spark plug?
2) Video I saw mentioned spark plug "Alignment" or bad things happen. Will Torque it self cause proper alignment?
3) What is Torque for 2012 e350 M276 - or where can I find these answers.
I use non-OEM plugs and they are fine.
Usually Bosch, NKG, or Denso.
On the box it says the torque (18 ft. lbs. )
Use a torque wrench.
What do you mean by spark plug alignment?
I have seen videos about "lining up" spark plugs to increase performance, but not required.
on this video https://www.youtube.com/watch?v=EiRAnh_wEjg
is where I heard about "indexing the Spark Plug"
Between (40 seconds - 2 minutes ) they talk about tips/tricks/TSBs
Does this make sense?
Wow.
This video makes an incredibly easy task incredibly difficult.
I have never, ever heard of indexing being required as the author suggested.
First, read a little about indexing to get some context, it is controversial: https://www.fordmuscle.com/archives/2000/07/indexplugs/
Plus, he uses a $600 torque wrench.
My digital torque wrench was less than $50.
What does that have to do with anything? Most mechanics I know (and I work at a dealership) don't use cheap tools. Almost all of them are using Snap-On or Matco, especially those that have been doing this stuff for years.
23nm is the correct torque. Check the last post here https://mbworld.org/forums/c-class-w...-question.html for a screenshot of the bulletin from MB showing why aftermarket plugs may not be aligned properly. Indexing is real and is done from factory on the 276/278 engines and their derivatives.
Joe1 - So if you use MB spark plugs, and torque them correctly - that will index them correctly - YES? no two way about it.
Also it mentions you might need to replace the 6 intake gaskets - YES or just reuse ?

Yes, correct plugs and torque puts them where they need to be.
You don't have to remove the plenum, but if you do, you can re-use the gaskets, just pull them from the upper part and put them on the lower half before you re-install.

Yeah I see what you mean. Im just saying that the video overcomplicared such a simple task. I didn't know you worked at a dealership. How cool!
I agree, but they might have a particular manufacturer that designs the threads so when torqued down to 23 nm the electrode is in the correct position.
