Hi all, I'm new here and this is my first post. I am wonding when do i need to change the sparkplugs and wire on my 01 clk55 and how much would it cost.
The car have about 68000 miles on it.

any info would help
thanks in advance

If they're original, the plugs were due two years ago. They have a 5 year OR 100,000 mile life span. If you're going to change them yourself, the plugs can be purchased for $7.50 each at the dealer with MBCA discount. The discount is considerably more than a year's membership in the MBCA. If you want the dealer to install the plugs, you definitely want to consider a membership because the discount on parts AND labor for that job must be more than it costs for a couple of years membership+.

Thanks for the info MarcusF
my local shop told me that it would cost about $1,000 is this about right?

1,000? I'll do it for that price to I'd recommend doing it yourself it's not that hard and it's a lot cheaper than the stealership..

$1,000?.... you have got to be kidding me...

There is a DIY on the Spark Plugs on here as well, I dunno where the link is right now but when I find it I'll post up or maybe Marcus might have it who knows.

1k for Plugs change/install is definatelly and is out of this world.

I just changed my plugs about a month ago and I have to say that IT IS A PAIN IN THE A##...but I saved alot of money using the DIY posted on this forum.

I do recommend getting a good spark plug wire puller that has a good 45 or maybe even a 90 degree angle on the tip of it. This will help out tremendously when pulling the wires from the back two plugs. There is not much room to work there as it is and the pullers made it easy. I tried without them for about 45 minutes till I gave up and went to Autozone and spent 15 bucks on the pullers. My plugs were worn the hell down so I am glad that I replaced them. My car runs much smoother now..OH and go ahead and buy some Mass Airflow Sensor cleaner while you are there. Clean that sensor while you have it taken apart. OK OK thats enough for now

Thank you all for the good tips.
I will try to do it myself this weekend.

Where is the MAF sensor located??? and do u really need 16 spark plugs for a 2001 clk430?

SUNILP

it usually runs 3 hours of labor for the plugs. Coil packs usually have to come off the rear. Plus, remember you have 16 plugs to change. DO NOT pull on the wire.

riannausa,
Yes you do need 16 spark plugs / twin plugs per cylinder.

The Mass Air Flow sensor is located at the rear of the intake manifold just under the air filter / air box assy. This piece which pops right off.


Then look to the back of the engine where the rubber air seal pulled off for this piece which is oriented with the waffle grille facing straight up.


Hope that helps.

riannausa

Thanks for the help! so is that round thing with the waffle cover the MAF?

I got quoted $540.00 from the stealership for 16 plugs PLUS labor.

MarcusF

I bought plugs from Mercedes Benz of Valencia within the last year. With the MBCA discount, they were $120.

BIG +1 on that
