Correct O2 Sensor Part Numbers

I am looking on Rock Auto and it is giving me two choices for the front O2 Sensors. Denso P/N 2349051 and 2349026. I have a 2005 4x4 4.0 MT. Toyota part number for front based on my VIN is 8946704020 but based upon the model year engine etc it calls for 8946704060. What is the difference in the Denso parts and which one is correct for my truck? Never had this much trouble buying O2 sensors before. Thanks

 

89467-04020 front ( same left or right )
89465-04290 -driver side rear
89465-04300- passenger side rear

 

So what is the correct Denso cross reference for the -04020 Toyota sensor?

On Denso website it says to xxxxx VIN, and from xxxx VIN. My VIN is 5TExxxxxx5Zxxxxxx. I am guessing my 5Z VIN comes before 6Z?

 

I just put in the oe # and got these two choices

 

This online Toyota parts dealer shows 2 A/F sensors and 4 O2 sensors for a 2005 4.0L. Scroll thru the list about midway down to see A/F-O2 sensors. The parts here line up with what was provided above in post #2 plus 2 additional O2 sensors:

Thanks! But how do then Toyota part number translate to Denso part number. It lists a cut off VIN but I’m not sure if mine is before or after cut off.

 

I would go to the Denso parts site for clarification regarding their A/F - O2 sensors.

Ok great, I tried to use their cross reference tool for 89467-04020 and zero results. When i search by year it gives me the same two part numbers. Based upon my VIN that I posted earlier, what part do I need?

 

If it's a Denso part you need clarification on, go back to the Denso site I posted above and click on "Contact Us". Be sure to provide yr/make/model/VIN - all of this. They should be able to answer your question.

 

I should have just done that and not bothered to post on here
