here is an actual short article from ngk... where they give both part numbers and say that plugs are available outside of mercedes dealers.
http://fr.ngk.de/NEW_AFTERMARKET_NGK...UG.2985.0.html
"NGK’s ILFR6A iridium spark plug is now available for fitment to 19 Mercedes models introduced between 2000 and January 2005 ranging from C160 1.8 litre Kompressor to the 5.4 litre SLR McLaren. The actual Mercedes Part Number is A0041591303"

I just got off the phone with MB, they say the longer one is correct, talked to NGK tech said that they(ngk) have the wrong plug listed and to use the longer one. I started another thread looking to see if anyone has a head off, I just cant imagine an engine running with a plug that far in the hole. The whole issue of this thread was due to massive carbon built up on the treads. leads me to belive theres more to this.

You have to first consider the website the 2 posted above are distributors not manufacturers website. You were not on ngk's website.
Here is ngk's recommendation > http://www.ngksparkplugs.com/part_fi...gineid=1465954
Their are also 2 different iridiums available from ngk > http://www.ngksparkplugs.com/product...x.asp?mode=nml
The laser iridiums are the oe plugs per ngk. The iridium ix is not even available for the e55.
The ILFR6A is the part # designated for merc by ngk since they are private labeled with the Merc logo on them. Also that link is for ngk europe.

I also just talked to a friend of mine who is a tech that works on my car and he told me he often sees Bosch plugs being used as well. I do not know the part number for the long Bosch plugs though....

Here are the part #'s broken down.
I = Iridium/ platinum. Iridium center electrode w/ Platinum pad ground electrode.
L= Short type.
F= 14mm o.d., 19mm/ 3/4" reach.
R= Resistor type.
6 = Heat range. 2= Hot 12= Cold.
A = Special Design/ Firing End Construction
-------------------------------------
I = Iridium/ platinum. Iridium center electrode w/ Platinum pad ground electrode.
F= 14mm o.d., 19mm/ 3/4" reach.
R = Resistor type.
5 = Heat range. 2= Hot 12= Cold.
D = Special Design/ Firing End Construction
10 = Gap of 1mm, .040"
As you can see the lfr's are the short ones & 1 heat range colder.
