So I have my nice shiny H23A with the auto MCJA and PCF ECU in my garage and I'm gathering parts for the swap. On the Accord Wagon this came out of it used a single A/F or O2 sensor and the part number I found for it is 36531-PCA-014 which goes for $245 or so online.Does anyone happen to know what the NGK/NTK or Denso equivalent part numbers are?

 

bump?
If not what have others used for their H23 or F20b swaps when using the JDM ECU (PCB or PCF)?

 

If anyone happens to find this post searching for the same info I've finally found the NTK and Denso replacement part numbers available in the US.

The Honda part number was 36531-PCA-004 which was superseded by 36531-PCA-014
The OEM for that part was NGK and the part number in that market was OZA501-EH4

After quite a bit of cross referencing part numbers between the few Honda models (all JDM) that used that specific part and a few emails with both Denso and NTK support
the closest match available to us in the states is either or
Those will work for anyone wanting to stick with the OBD2 setup using a PCF or PCB ECU, possibly others.
