Where to get o2 sensor? What brand?

[I support common sense]

I need at least one o2 sensor for my 1999 ford ranger 3.0 flex. I noticed it was discontinued on the ford parts catalog. Where do ya’ll get yours? We put a Bosch air fuel ratio sensor in a Toyota sienna and it performed poorly until we got the oem model. I’m wondering if that’s true for ford as well.

Unfortunately that's the case with almost all parts these days - even the quality brands can end up slightly off spec which can cause all sorts of headaches with sensitive systems like emissions. I do see that Rockauto has at least one Motorcraft part in stock but it ain't cheap. One of the techs on here might know if there were other OEMs Ford used. Otherwise, I try to stick to Japanese/German parts like Denso/NTK/Bosch etc. just hoping for a bit more quality.

That rock auto part was for the downstream sensor, I need the upstream sensors, but thanks anyway.

Considering what is available I'd probably go with the Bosch. They are the only one with the big body like Motorcraft and the same color connector.

I went with NTK's on my 96 as they were the folks who supplied Ford with their o2s during that period of time.

So, is there a 3.0 expert that knows whether it was Bosch or ntk?

Go back to rock auto. They have the Bosch upstream and downstream under $30 each.

I saw that, but I found the Bosch ones cheaper from Amazon with free shipping.

My original ones have both Ford and Bosch engraved on them.

The problem with Amazon and the like is that a lot of times they are fakes. Of course parts stores aren’t immune to fakes either but it’s less likely. Fakes have become a real problem lately.
