So if you opened this thread thinking I cannot find the O2 sensors, your wrong... my question is should a buy a universal O2 sensor as some guys have or should I buy a direct toyota/lexus replacement? ... any recommendations?

thanks

 

Get the oem ones for ease of installtion. If you don't mind wiring and need them right away you can go with aftermarket such as bosch. I believe the oem ones are a tad higher in price. As for me, I went with oem.

 

I would go with OEM/Denso, when I changed my O2 sensors, one was OEM/Denso and the other one was a Bosch, the OEM one looked fine and the Bosch one was somewhat melted.

 

 

I guess OEM denso's it is... any recommendations on where from? I guess I will order them from the denso site but I didnt know if anyone had a better suggestion?
