Oxygen Sensor - Universal vs. OEM Oxygen Sensor

[ntrcptr]

I'm in the process of replacing transmission. Wanna be pro-active and looking to replace O2 Sensors while transmission is out. Should I replace all four?(there are four if I'm correct?) Or just the though to get to Front Position O2 sensors? Upon research I found that there is significant price difference between replacement options (see example below). Universal is cheap but is it worth it? OEM is well... pricey. Then there seems to be a less expensive alternative to OEM. Any thoughts on these? Any other options?:vhmmm::pop:

Universal sensor is the same as others, for oem you are paying essentially for plug and play.

I know there are cheaper option for OEM. Try searching with the Bosch part number instead of the audi number. I seem to remember closer to 120.

I just got this done. I went with OEM, sourced from Audi dealer. They did the work. I saw the pieces, they were quite beautiful little plug and play things.
5 years of peace of mind hopefully. If you are adept at doing it, I say go with the cheaper. The fundamental function is probably identical.

paying for the plug. certified RS6 tech told me to just buy generic Bosch and splice.

Yup..just spliced both of mine with cheapies....
