Anyone know how to change spark plugs for 220D, "08??
So I left the Camera at home and I didn't get to do the DIY for you guys. I'm just trying to break it down to show you how easy it is.
I guess this would be a more advanced DIY since I'm not really showing you what I did. but it's basic common sense right in front of your eyes.
I bought the newly released NGK spark plugs to replace the OEM factory Denso spark plugs.
Tools:
10mm Socket-----RED
12mm Socket-----BLUE
12mm Wrench-----BLUE
5mm Allen Key-----GREEN
Intake Mani. Gaskets (3 Pairs)-----YELLOW
Extension
Spark Plug Socket or 16mm Socket
I've marked the pictures with certain colors as to what tool you will use.
Pic 1
Pic 2
Pic 3 - All you have to do is remove the Intake for the left side spark plugs.
Pic 4
Pic 5
after you remove that there should be connectors attached to the spark plug tubes. remove those. each tube has a 10mm bolt holding it down. remove that. then use your extension and spark plug socket to remove your spark plugs.
hope this helps!
sorry in pic 5 it says look at pic 4 for reference but it's actually pic number 1. pic 4 was the file name :X
Heres the Link to the NGK spark plugs thread.

this took me about an hour and a half cause I didn't really know what to do at all. and that 12mm bolt behind the manifold is a BEEEECH
I have about 67k miles on my car. My OEM stock Denso plugs were still pretty good. so those who debate on changing them at 60k or 100k.. they will last till a 100k np IMO. I just like to change stuff out early to make the car last just like how I change my oil every 3k with synthetic when it's not necessary and can last till 5k. lol

Wish I Saw This Earlier
After an hour of frustration (and multiple cussing sprees directed at an inanimate object) I stumbled upon this post of yours. Can't thank you enough. I had tried everything to get this bolt out (the recessed one in the middle of the intake) and as soon as I hammered that 3/8 socket over it came right out. Thanks again.

Coming up on 160K miles, Replaced the first set at 60K, since they still looked good I waited for 100K this time. From my experience working on older cars, one would usually replace the spark plug wires too when replacing spark plugs. I don't see needing to replace the spark plug harness that my IS250 has, but has anyone had any issues where the harness needed to be replace or are they just that well made that they will last the life of the car? Glad to see this thread is still here.

On the other write up it says "I will suggest to do it one plug at a time. Also, remember the order of wiring connectors. This is very important." What does this mean??>?

I'm going to embark on the DIY in the next 3-4 weeks. I have the parts and tools all set. I have done a DIY on a Toyota Camry the other day and i must admit it was easy. Doing it on a 250 and reading that you HAVE TO remove the manifold i'm abit concerned. But it got to be done!
I notice when doing the Camry the oem Denso plugs unscrew with abit of resistance (makes a screeching noise with every turn). It isn't that bad but when the plugs comes out it's all brown (not rust but brown). The car's done just under 63,000 miles. Would the brown on the thread be due to no anti-seize apply from factory? If so i would put anti-seize on when i do the 250 (but only a slight amount)
Btw, the plug socket i have is magnetic and clings onto the plug so there is no fear of drop it on the way up (or down).

Picture of this but driver please. I thought I could use a normal 5mm Allen key that comes with them furniture install kits.
Would this do the allen bolts? I'm worried its not strong enough.
Or this one i think it's 1/2" drive.
