Getting a bad O2 sensor error and it's time to replace them.

Getting 3 different part numbers from Autohauz.

Any idea which ones I need.

Is pre cat but the first O2s are gone obviously since I have long tubers.

Thanks in advance.

here is the link to Autohauz so you can see the ones I am looking at

Weird, looked online at Benz Parts catalog and can't find anything definite. Maybe I will just go universal.

The info below is from the Bosch website:

You can either go with universal replacement O2 sensors, part number 15733, front and rear (requires splicing into your existing connector plugs), or with direct fit - as in direct plug-in to the factory engine wiring harness, using part 16272 for the pre-converter, and part number 16328 for the after converter sensor. If you're doing a complete replacement, you'll either need four of the 15733 universals, or two each of the 16272 and 16328. As an aside, Autohauz didn't have the best O2 sensor prices when I bought my spare set. Do a google for the Bosch part numbers and some comparison shopping because these things aren't exactly cheap.
