so since it's been awhile since i've actually written a DIY, might as well do a quick one
first things first, removed airbox (pops up) and the tubes to make some room

no airbox in the way=more room

next i'll have to remove the coils to create even more room, but first i'll take some pix for referance just in case i need to see where the wires go back




pretty simple, short wire low, long wire high


using open ended wrench to "easily" remove the baked wire, propping against the valve cover

yes, i told you it's baked

FTMFW? hmmm no

Yeeeeeeeeeees! one coil out 7 to go lol


oh yes coil is held on by one torx T27 nut, almost forgot to mention
this is a good time to clean around areas where no MB tech will, they just don't give a foook about your dust/dirt, just a rumor ;p

prepared my spark plug socket, that extention was a little long for the drivers side so used a smaller one...
good thing to use a little electrical tape on the socket that way you can never drop it, easier to play with it while you remove the spark plugs

flex your muscles

first one is out

hmmm hold on a sec, I thought it's supposed to be 100k right? riiiiiiiiiiiiiiiiiiiiiiiight

junk, trash, garbage
(only 49k on them btw)
wires baked on them, gap pretty big (i don't have a measure device but it does look too big by my eyes), etc. etc.


clean around some more

there you have it, pretty much a breeze just make sure you're careful with your hands around the heat shield on both sides, very sharp ;p
it's not that bad really, i think my X5 was more of a pain this weekend due to less space to work with on the drivers side

so now you may wonder why no pix of installing it back, lol
well my parts are not here yet, waiting on Magnecor wires and new spark plugs to be shipped
Eurosport

 

 

great DIY.
Did you replace the ignition coils/wires?
I'm not techie, but MB wanted tons of money for the parts plus several hours of labor to replace both wires and plugs.
Also, they wanted $20/spark plug at MB.

 

Well Jamesparkowire, here you go and I was just about to take pics of this same job but thanks Eurosport, now I don't have too, lol...

Btw, my Magnecor wires just arrived drop-shipped directly from Magnecor, how great is that!!!

 

Already saw it Jumbledore!

 

Superb..Thanks Eurosport!

 

I'd be worried about something getting into the cylinders while the plugs are out for an extended period of time but other then that the job looks pretty straight forward and easy.

 

sweet write up.. i need to do this.. can someone come over & do it with me??

how much do the OEM wires cost online..?

 

Drive out to LA and we can all do it together...

 

I remember this job, looks about the same amount of clearance. Maybe a tiny bit more room than the 202. It took me a while that day. @ 60K when I changed mine they were in the same condition as yours.

I've had the magnacore wires with NGKs for over a year now and they are great. No issues. I due wish that I bought some heat sheild wire sleaves for added protection before I put everything together. Its very hot and close in there. Looks good.

...I thought the 210 55 used the green injectors like the 43 but I see yellow?

 

do you know whats the their flow rate? Bosch greens once flow 450CC, and I thought yellow got a less a flow. but I am not sure, thats why I ask

 

ok, my wires finally arrived yesterday, installed them (i had new spark plugs already in, bosch platinum single electrode...)
all i can say is damn lol car feels good,
before the plugs change there was a little engine vibration you could see it at idle (and no my motor mounts are perfect ;p)
that is gone, at idle is just very smooth right now
took it for a spin, felt very very good, very responsive, also outside temp might have helped (45F)
i could definitely feel it was pulling a lot stronger though specially between 4k-5k

i don't know how much the wires helped since i did wires/sparks at the same time, i can't comment on them besides, the quality of them is great

and to Ohlord lol and his 100k intervals on plugs, i say bs
that's all

 

I did my plugs this past weekend. Thanks for posting the pictures, the 55 motor looks the same as mine when you pull your air box off. When i pulled one plug out for inspection i noticed the plug wire to be in great shape so i chose not to get new ones. I think the plugs had been done once before i got the car i now has 120k miles on it. The 17mm wrench worked great one thing i would like to add is on the rear drivers side bank i could not access the metal part at the end of the pulg with the 17mm wrench so i put a zip tie around the metal part and pulled on it from there ( i guess you could pull on the wire if replacing them). Thanks for the post!

so where would you guys recommend ordering the spark plugs and/or wires ?
I need it for a '00 E320 which has 91K miles

 

get the wires here for a great price.

I would recommend these Bosch Spark Plugs...they're the direct replacement for Bosch F8DPER which your owners manual recommends....AND 16 plugs will run you around $85 shipped.

Just noticed this is for an E320....less money for you!

Jim

 

thanks Eurosport. Do you always work under the hood with a nice watch on?

 

+1

 

Is the process pretty much the same for the 06MY? Can anyone tell me the part numbers of the OEM plugs/wires?

 

how come there is no spark plug for W209 chassis I looked everywhere but didnt see from that site.

Eurosport,

Where did you get your spark plug/wires ?

Andy

 

I changed all 16 plugs today as well, pretty easy job despite all the hype. If you know how to change 1 plug, you know how to change 16 of them

 

Might want to consider replacing the valve cover gaskets whille everything is already out. They WILL leak if they havent started already. Saves time having to remove everything all over again. Besides there like 20 bucks for both sides. Just my 2 cents.

 

Euro! what yr is ur car? i see you have the 1-5-4-2-6-3-7-8 firing order. is very extrain if you see the engine & review the firing order sequence in the pistons. the 2 final fires are 7 & 8 (same side) one back other. i can't understand why. my car is a 99 & the firing order is 1-5-8-4-6-3-7-2 is a little more ordered if you see the engine sequence, i understand they don't affect the engine performance, but i think the camshafts need to be different in the models with this firing order. is your car pre-updated or post-up..

my car has green fuel injectors i see your car has cream ones. i think your car is post updated right?

thanks in advance

Great DIY post, Eurosport. BTW, the dealer charges $25 a plug x 16 = $400 for our cars. Labor isn't as bad at $235 as quoted, but the whole deal is still $635+. I wonder if you could buy the plugs for $160 and then have the dealer install?

Also, I think the 100K miles intervals is a little too long myself. I had mine changed at 57K miles, and it feels a lot crisper.

 

i got wires from the Alamo link above
spark plugs i usually get them from http://www.autohausaz.com/

 

yes they are all the same, same engine, even other MBs, all have same layout
