I see lots of info here, but its fragmented. I watched YouTube video and found the location of bank1 sensor 1. Can someone please confirm this Denso 234-4355 will fit?
The car had done 283k miles. Should I change the one closet to the radiator as well?

Prices on Amazon for this is around $33, but I see other places that are more than double this? Is $33 normal?

Is the sensor after the catalyst the same sensor? From what I gathered here, It seems not as the wires are longer.

RockAuto has them as shown below before shipping. There is a 5% discount code in the vendor section.

If you input the vehicle data, into RA, it will show that NTK is the 'Actual OE Part' though a little more $$.
IMHO, I would replace both front & rear at that 283k miles interval.

NGK NTK is OEM not denso for oxygen sensors. Factory sensors on my 2004 TL and 2007 TLS stamped NTK JAPAN.

 

I tried again, to remove the connector. I was unsuccessful. In the I took it to the shop. They used my sensor and charged me $45 for labor. I put back the brace across the engine bay.
