Mileage vs Age for Plug Replacement
I have a 2010 E350 which has done 44,000miles.
Dealer suggests 60k/6year service which includes replacing spark plugs.
Any comments on whether that is necessary since mileage is low.

i would imagine the plugs are run time based. however for the purpose of vehicle value, completing the entire suggested 6yr service will make it easier to sell your car when the time comes. Picking and choosing won't give the next potential buyer and warm and fuzzy.

I agree on the run time and would consider pushing 6.5 maybe 7 years if miles were low. But not 8 years if the plugs were never done on OP's 2010.

What can wear out on plug based on time?
Common idea behind time limit on plugs replacement is avoiding corrosion freeze, but modern MB have very little rust and even on 10 yo car most of the bolts can be unscrew by fingers.
350 engine has different schedule than 320, but I had funny experience with 320.
Bought the car with 146k miles and getting copy of MI I read the plugs were replaced at 108k.
Took me couple of years to re-read the parts number to find I was mistaken and those were different parts, not plugs.
So at 170+ kmiles, 13 years of age I replaced the plugs.
The old ones had the platinum wire much shorter than new plugs, but I am observing mpg at each fill up it did not change at all.
On old plugs the engine would occasionally jerk from the idle, when 4M amplified the issue, but I am not totally sure the new plugs cure it.
I sold the wagon short time after.

I also have a 2010 E350, with slightly more miles ~49K. My brother did the spark plugs for me in 1hr.
The old plugs were in pretty good shape. I guess you could run into problems the longer you left it in there?

How much was it at the dealer? They're pretty simple to change on the M 272 engine. There's probably videos on it on YouTube and it's mentioned in the old threads. I had an indy do mine before and it was under $100 including the plugs. I think it took less than half an hour as he was doing a bunch of other things at the time.

The Bosch plugs have been uneventful ☺ which means its running fine. I really just changed them at just under 60k miles to make use of a RA gift certificate. My opinion is that you wouldn't really notice any difference in the 2 brands in a stock engine application.
Unless there's a good reason such as tuned or modified engine I tend to stay with what the mfg originally installed.

I have those in my W211. I got those as when I searched the old threads, those seem to be the recommended ones. But there doesn't seem to be any bad ones so NGK or Bosch should be fine.

you might be right about noticing it tho , unless the engine is tuned or chipped maybe.
bosch come up 20 bucks cheaper.
What im thinking is that since ive never changed them in 120k miles , new bosch will perform much better anyway.
even tho i still get decent mileage. Sooo yea.. anyways.
will report back after i get my project done.

You'll be fine.
I've read a lot of "these [mfg] plugs are great!" when it really seems the improvement is just from installing a new set of plugs, especially when over 100k miles.
NGK is oem on many vehicles and nothing against them, I use them. But in this case I don't find any issue with the Bosch beyond personal preference. That's ok too, you can use either.

I got the plugs today , so since i am so impatient i had to get it done right away.
whem i pulled the first one out , i found that original ones are NGK lol i was like no way , but yes... NGK R1 and replaced them with Bosch double platinum R6..
the job is straight forward.
it was time for them to be changed , glad i did , for 55 bucks. Thanks everyone for the input.

Good pictures. I put a scale on 2nd comparison and the gaps are the same.
So no wear out that you can see. Can you measure?

Looked like time for a change! Lots of deposits. Was surprising to see what the previous plugs were - are you the original owner or perhaps they were changed out at some time.
I'm currently rebuilding a 99 civic 1.6 vtec engine and installing the same as oem NGK plugs ☺

NGK is a Japanese brand as far as i know so should be perfect for a civic.
ill give bosch a try , its my first spark plug job.. next time if it ever gets to that point ill go with NGk.

Is there such a thing as a spark plug break in period??
just curious
The car starts and idles good with no issues , but from first observations looks like the mileage has gone down , i only drove like 20 miles ever since to observe more to make sure , but wanted to hear some opinions?
swapping NGK with Bosch or vise versa make any difference?
