I've already had one Bosch that was bad out of the box. That's the only thing that's sold locally.
So, what should I be ordering? Thanks

AC Delco or Denso. Those have proven to be the best on the 3800's.

Do you have a part number for the Delco? I think I can get a Denso, but have to order that one as well.

How does one change the female connector as well? The description of the part shows it has a terminal of some type on the wire.

NTK makes excellent oxygen sensors. They're OEM on many Ford vehicles. Denso makes nearly all the sensors for modern GM and all Toyota cars/trucks.
Those are definitely the best two out there from what I've seen in the aspects of performance and longevity.

What problems did YOU have with your Bosch?
My first one was DRT right out of the box
