Goter done! Thanks again for the thread. Used a torque wrench but you were right you don't really need one you can feel it. One thing I didn't do was disconnect the coil, just popped it out and took out the plug. Also changed bank 1 o2 sensor, was more of a hassle then the plugs but overall very simple jobs. Noticed quicker response and more torque. My baby's back to peak performance!

Great Do-It-Yourself.
I just replaced my plugs with help from this thread. It wasn't very difficult to do all of the work myself. I found the NGK plus on ebay and the 14mm deep socket for $6 locally.
Saved a pile from the stealership.

So here goes my shot at a DIY for replacing M156 engine spark plugs. As you saw in my thread posted last night https://mbworld.org/forums/w211-amg/...-insanity.html I had dis-assembled the intakes and air boxes to add a reflective tape used in Indy and F1 cars for reflecting heat away from the intake air. Besides trying to reduce intake air temp, it looked cool. So here we are in the AM with all the parts on the side. The top of the engine is easy to access. First I loosened up the wires to the coils on the top of each spark plug. You should be able to pinch the connector to un-clip it, but I found just using a screw driver to be easiest. The torx screws holding on the coils were lightly hand tight and easy to remove. However, the one closest to the fire wall on the left side had limited clearance. Took a mix of sockets and adapters to loosen and replace this one. That is the fuel line. I did not bother to buy the appropriate spark plug socket since I had a deep 14mm socket. However, to remove the spark plug once completely loose, I just stuck the spark plug boot/coil in there and captured it. This happens to be a picture of a ne wplug ready to go in.

I don't know the MB tool number but for me my regular spark plug socket was too big so i had to go to Sears, I always buy craftsman so its my go to place to get the right socket. I ended up getting GearWrench KD3938 9/16" Socket that has a flexible joint. It worked perfect for me. Cost around $18. Spark plug fitted perfectly with no problems. Hope this helps and Good luck. For me it was a very very easy job.

I ordered these.
I have heard not to use anti-seize???

Searching around now I see where NGK recommends not using anti-seize cause their plugs have a coating that doesn't require it but for MY piece of mind I did apply anti-sieze on mine. With the temperature these engines see and aluminum heads i don't see where you it won't hurt to put a bit of anti-seize. They say it can lead to over-torqueing the spark plug so i guess each its own. I had both electrical grease and anti-seize so might as well use it if i have it.

I skipped anti-sieze on BMW and the E63 with NGK plugs:

Also, thanks for the positive responses for all of you who found this thread useful. Now just gotta find time to type up the intake manifold gasket changes.

Nice write-up.
For those considering changing the intake manifold make gasket, make sure you get the updated gasket and bolts and torque to speck. The job is very straight forward with only a couple of pain in the rear parts when disconnecting all the hoses attached to the rear of the intake manifold. The early E63s are prone to intake leaks and the gasket change will fix that.

Many Thanks!!!
Just wanted to take a moment and thank the author and many contributors on this particular thread. Due to the detailed pics and instructions I was able to change my spark plugs, air filters and oil today saving tons of labor hours. Many thanks to all...

I did notice squeezing the throttle at low rpm 1500-2000 is much smoother now though.

Just finished following this write-up; very helpful. One thing I did slightly different, as
MBenzEnthusiast mentioned, was to leave the coil packs attached to the wires. I have a nasty habit of breaking connectors like that. So instead of using the coil pack boot to retrieve the loose plug (and to start the new plugs), I just used a 12" piece of rubber tubing. The same size tubing that fits the brake caliper bleed nipples (3/8"?) works great.
