What is the AC/Delco p/n on the heated O2 sensor?
What is the Denso single and three wire p/n?

TIA

There is nothing wrong with the stock AC/Delco part.
There was another brand O2 that in the car and it went bad.
My friend is wanting to either use stock/ heated or the Denso O2.
He isn't on the net much and askred me to find him the part numbers.

Denso 234-1001 is the part #

I have one in my car and it worked good using race gas, but im over the race gas thing now.
