Would these o2 sensor work on my truck and are there any other alternative part number that would also work ? ( Nelson Velez, 03/15/2024 )

You will want to confirm with a GM dealer but according to the information we have available to us, the part # for the RH sensor is 12565414 and the LH sensor is 12565415.

That is the correct part # for those .

I have a 2001 W20 chassis with a 8.1 vortex. The O2 sensor plug appears correct except that a tab and slot inside the plug don't align. Your site indicates that a trim is necessary. Do I open the slot on the O2 sensor plug, or trim the tab inside the wire harness plug? Thanks in advance. ( Ricky Hunkins, 10/01/2023 )

We find it is easier to trim the sensor plug than the vehicle side plug.

I have Banks Power Pack Stinger System GM 8.1L on a Workhorse Chassis Motorhome. Is this the correct oxygen sensor for me? ( STEVE HAROLD MAYER, 10/31/2022 )

Yes, the oxygen sensor does not change with the addition of the Banks system.

Is this the correct O2 sensor for my VIN? or am I needing the 12565414?

Thanks ( Gerald Aubin, 05/09/2022 )

Can you double check the VIN ? It's not showing up as a valid VIN, but using the last 8 digits pulls up 5B4MP67G723345682 , showing a 7 instead of a 5 after the "G" .
