I did the plugs on my E320 last October. I also recommend removing the coils since the plugs are difficult enough to get at.

I used the snap-on spark plug remover tool. The number on the handle is SBP 3, but you might want to check out snap-on's web site to verify.

If your plugs have never been removed, expect a fight to get them out. I suggest that you twist the spark plug boot to break them loose and do not pull on the spark plug wire (it may separate from the boot).

I used dielectric grease on the porcelin and the inside boot of the plugs so that they will come out easier next time. I also used high temp anti-seeze compound on the spark plug threads for the same reason.

Expect to bend your hands since the plugs are not very accessable.
