Just did spark plugs.
Dealer quoted me $423 for a spark plug change. What a laugh. It's easier than changing a tire. Takes about 90 minutes to do.

Good to know. My dealer quoted me over $500. I orderd the plugs and a now just waiting on some free time. Anything tricky in the job? In my truck I had to remove the fuel rail and injectors to get to the plugs which is a pain. Have yet to look into the ML63 to see how involved it will really be...but $500 for plugs just seems crazy to me!

We carry OEM NGK laser iridium plugs for $10.86 so that makes me wonder how much they are trying to charge you for labor and parts. Either way, that is a very high quote for such a simple job.

Here is the link to the plugs if you still need them:

Its a piece of cake. Just remove the top cover plastic and the air boxes. The spark plug coil packs are right there on the valve covers. Unscrew and disconnect each one and you are set to go.

I torqued them to 20ft lbs. You should NEVER gap spark plugs. ALL plugs come pre gapped. Gapping weakens the metal and can break off in time.

they charge $21 a plug plus labor. SO thats $168 for the plugs. And $222 for labor. plus tax. Sounds about right. Clock time prob shows its a 90 minute job. At $150 an hour its right on the money.

Thanks. I always like to double check gaps anyways. I have seen plugs gapped incorrectly too many times. if done right there is no risk of failure.
