Correct. And this is the best price I've found:

so the bosch part would be fine to use? i don't need to go oem? getmercedesparts has it for $243.20 + tax + shipping probably...

i believe this is the first time i've had to replace o2 sensors... i'm almost at 90k miles...

bluejae

will try and replace the sensor with a friend... anyone done this themselves? is it hard to reach? any special tools that may be needed due to tight space?

thank you

Bosch is the OEM manufacturer. Just comes in a different package from MB.

I just used a long open-end 7/8" wrench. You can order a special socket as well if you want.

Mr. Lin

or buy one from fcpeuro and they've got that warranty j/s

Great example of how I get slaughtered daily by Amazon on Bosch products however I do have the best warranty in the business
