W208 - Spark Plug and Wire replacement procedure?
Hello Folks,
I have a 2002 CLK55. I need to replace the plugs and wires.
Is there a special tool used to pull off the spark plug wires from the coils and plugs? How do they disconnect?
Also, what special tools would I need to get to the plugs at the back of the block?
Any suggestions on where to get the parts?
Thanks in advance.

To access the hard to get to plugs, I used a ratchet with a flexible head and various extensions.
For the plug wires, I used a spark plug pulling tool. These are available everywhere, and allow you to remove the wires without ruining them.

Notes:
- Removing the washer tank added a lot of room to the driver’s side.
- I left the plug wires connected to coils and did not disconnect the coils from the wiring harness.
- Any time I pick up a wrench, I wear gloves. It's easier on the hands. If you usually don't, give it a try. You may be surprised.
- I got my plugs from my local dealer - with the MBCA discount, 16 plugs were $120.

where to get the special 17mm boot removal tool but if you have ever done it the other way with the pliers you will wish you had one.
Your engine can use oe plugs and the best in performance in that range are the
BKR5EGP NGK 7090 about $2.79 each.Do not fall prey to the multi tip plugs on the m113 engine.
Why are you replacing the wires?If they have not been abused by improper removal the oem wires will last the life of the car.
extrapolate what you need from the w210 diy of plugs on benzworld.org w210 diy section.
We just had a diy tutorial with some E class owners and one C class owner several weeks ago on the w210 section.Proper extensions,a torx bit for the coils and the 17mm tool and they were done in under two hours their first time.
use no anti seize, have two 5/8 in thin walled sockets one with the rubber spark plug insert for removal and one without so you can easily withdraw it from the plug after installation.Make sure the ratchet wrench has the push button release.Per above a swivel or a short 3/4 inch extension and an assortment of other extensions makes the job more enjoyable.
if you need any more tips pm me and I will shoot them your way.

I'm looking at buying the same plugs by NGK: BKR5EGP. The owner's manual calls for NGK: PFR 511.
Anyone know what the difference is?
How does your car run with the BKR5EGP? When should they be changed again? Also, did you have to gap them when you installed them or were they pre-gapped?

Why am I in disagreement? Google anti-seize and NGK. When you find the NGK tech bulletin, read it carefully. Then ask yourself, why does NGK say no anti-seize is required for the initial installation, but if you ever remove them and reinstall, use anti-seize? Things that make you go hmmm . . . . . . . I think you should use whichever method you feel most comfortable with. Having been a Porsche wrench and having seen numerous stripped out heads (many of which I turned the wrench in the stripped head), I feel comfortable with "der seize no". Others don't.

How do you reach the rear plug boots with the pulling tool?
Thanks.
