O2 Oxygen sensor
« on: May 28 2021, 06:58:10 PM »
Hi All, It seems each member claimed one oxygen sensor is better than the ACDelco
Highway stars claimed: AFS-21 ACDelco one wire (non-heated, original equipment) Oxygen Sensor for 1984-1987 Vin 7 Buick Grand National, Turbo Regal, 1987 GNX, and 1989 Turbo Trans Am, supersedes both ACDelco AFS-20 and AFS-22 oxygen sensors.
Yet others claimed Denso is better
Which one is supersedes all?

I’ve had better luck with the Denso, so have stuck with what works best for me. Each to their own , I guess 🤷‍♂️

I have tried the 1st two types, and the 3rd will be installing:
ACDelco AFS-22
Denso
ACDelco AFS-21

Which part # do you use for Denso?

A lot of broken parts does not make you a racer; it makes you a slow learner.
