What o2 sensor are you guys running with the 24x conversion? I bought an engine with a BP harness and it says to use ac delco 213-1325.

Just curious if that's what to run? They seem a little hard to find. AutoZone has none and I believe summit racing also didn't have them. I have found some on eBay and amazon.

Thanks

The sub of the AC Delco ADO-213-1325 is Delphi DFP-ES20317 or DFP-ES20023.

 

Stock AC-DELCO.

KW

 

AC DELCO with flat 4 wire oxygen extenders. Either that or the AC DELCO Corvette ones.
