I'm looking into changing the Pre-cat oxygen sensors, but i'm having trouble finding and verifying the DENSO part number. The place I usually purchase from only carries "walker" brand for the 3rd gen TL. anyone have experience with "walker"?

so far I've found only amazon having a Denso part number of "234-5010" that they say fits, anyone using this part to confirm?

also, anyone tried using an oxygen sensor from a different honda? I'm thinking about "denso 234-4096" or "denso 234-4099" they're also 4 wire and the threads should be the same?

if i really can't find denso, OEM part number 36531-RCA-A02, and 36531-RDM-A01 correct?$135 each before shipping is what i found, anyone experienced better?

 

I suggest going with denso only since people get random CEL and misfiring with non-denso. I am not sure about the different part numbers. I wish I could give u more info

 

i went to take a look under the hood today instead of just looking at part pictures online and apparently the O2 sensor is 5 wires.. lol so i guess sensors from a different honda/acura won't work
