he claims it is OEM... You should email him and ask if it is a Bosch insert. He listed it as a Bosch insert, but who knows. Usually the ones that are not OEM say Bosch part # or Mercedes Part # for reference only.
I think the Bosch MAF insert I bought had the green O ring. It was awhile ago... Either green or red... I forget.
I think I paid $90 shipped for an OEM Bosch Maf insert from ebay. For the price that he is asking, I hope its for a new OEM Bosch insert.
Good Luck

I just recently bought a Bosch insert, it came in a yellow Bosch box and the O ring was green like in your picture. If you don't trust the seller, ask for a picture of the other side of the sensor, it will be stamped with the part number and say Bosch right on it.
Remember, to swap these out, you need a FIVE sided security torx, these are super hard to find, as everything on the market is SIX sided security torx.

Last time I checked, Sears didn't sell 5 sided security torx, do you have a Sears part number?

What I did was I took some putty and pushed it into the screw head and took that putty to Sears to match it up with what they had. It was an exact fit.
Here's a link to Sears.com that has bits similar to the bits I remember buying.

The security torx bit on the MAF not only has the center pin, but the torx is five sided, so regular six sided torx won't work. I couldn't find any five sided torx bits at Sears or any other place, found a set on Ebay which I purchased and of course, now the T25 is lost, so I need to purchase another set or just a T25, thankfully I am done with my MAF, assuming of course, I don't try to install the M113 maf that I have.

I was pretty sure mine was 6 sided so I just went and took a look at my engine bay. You must have a different torx screw in your MAF because mine is 6 sided and has the same hexagonal pattern as the bits in the above link from sears. Must be a different screw used in different engines and different years on our CLKs.
Glad it worked out for you
