Greetings all.
As promised, I did the plugs today.
It is a bit of a chore, but no real tricks involved. Just lots-o-tight spaces.
You will need a few special tools, including a slim profile spark plug socket.
I used a Stahlwille socket#51, a 16mm socket with rubber insert.
A T27 Torx bit and a Low Range torque wrench (for the Torx screws- 8Nm),
and a regular range torque wrench for the Spark Plugs (28 Nm).
Another tool that made the job easy, was MB part# 110 589 01 01 00, aka
Hazet # 2771. Lucky me, it happens to be the same tool used to adjust the valves on the Old 280GE. Two for the price of one! You can actually find those
floating around on Ebay for cheap. It is worth every penny for this job. You use the wrench to pry the spark wire off the plug.
Other helpful items were 3" and 5" extensions, and a U-Joint.
In all, it took around 3 hours. A preatty straight forward procedure.
Although the coils and plug/block areas ARE marked with A & B, I was paranoid, and just did one plug/plug wire at a time, JUST IN CASE!
PLEASE NOTE!! AFTER RECHECKING THE COMPANY'S WEBSITE, THE SPARK PLUGS **DO NOT NEED!!** ANTI-SEIZE PASTE!!!
Spark Plug update RE: Stahlwille Socket " 51 16 mm
G-AMG,
Will I need this reduced socket on my 2000 C280 V6 engine (202)
I am trying to id the proper spark plugs in the owners manual it states
Bosch F8DPER however, after going online I can'r seem to detect this partumber.
Is there a update to this plug with another P/N. Other on line parts sources don't show this P/N. Can anyone advise about which is a better plug Bosch or NGK. If so, can you advise P/Ns for each. Got about 60K and its about time for a change of plugs.
For E320 V6.
It is difficult to remove the spark plug wires on this V6 engines. This is what I did. You can give it a try. Pull your wire strait out in the direction of the plug.
This might work for you, it worked for me with no problems.

only need to remove the plug wire from the boot end and leave the other end fixed to the coil.You do this the proper mb way with the special 17mm offset tool mentioned above and on sale from me for $28 delivered stateside.Makes the job a snap,pops them off ,helps pop them back on and no damage to the wires.
ngk7090 plugs are oe and the closest match to the oem platins that work so well.They are only $2.75 at most auto stores.No anti seize needed they are plated in a dry metal anti seize.
pm me for shipping info on the boot tool,the transmission dipstick or the boxed set of dash cluster and radio/climate control removal tools.

Hey, folks. I have seen some creative ways to remove these boots from the plugs, but however you do it don't ever pull on the wire itself. Never. Your force should always be exerted on the boot only and as noted in the same plane as the plug angle to the head. This rule/advice is not limited to MB vehicles but all cars; it is just far more critical on these engines because the wires are $15-$25 each depending on if you buy them individually (and where) or as a complete set, and they are easily damaged in part because they fit so tightly.
While hilarushi's solution is creative -- and almost free -- I think the physics involved would impart a partial angle to the pull, which is probably okay but might increase the effort needed. In any case wrapping the wire around each of 12 plug boots is lots more effort than the 17mm offset wrench or the Lisle tool.
Take care and enjoy the ride,
Greg

1999 E320 Wagon 93K, Changed my plugs (NGK 7090) last week - first time I had ever changed spark plugs on any vehicle. Took about 3.5 hours but I was taking my time. I didn't run into any major snags - the old plugs were really screwed in tight though. The Spark Plug tool sold by Oh Lord was critical. It really made pulling the boots off a snap and what became quickly apparent was its usefulness getting the boots back on in the confined space. The drivers side plugs look more difficult but they were actually the easiest. My electrodes had worn out to the point that they were all showing a gap of about .45 (vs the recommended .39/.40) but the car had been running fine. I just changed them since the car had so many miles on it and I am getting ready to leave on a cross country trip. This is a great website for DIY maintenance and I will post anything I can that may help out someone in the future.
