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.

Don't buy auto parts on Amazon. There are counterfeits of everything out there. If you order something try to find the same thing locally and compare packaging and the parts.

My 98 still has the factory o2 sensors. Some years ago, I installed a 160 thermostat so the computer would not switch from open loop to closed loop. So the o2's sensors are ignored in open loop. Runs GREAT! When I scan the computer, no codes. ZERO, ZILCH, NADA. Still gets the same gas mileage it always has.

It's cheating. I know. But we don't havesmog checks here. And if we did, likely 25 years or older exempted.

For whatever reason I believed if it said “Bosch” under the store name on Amazon then it has to come from Bosch. Which is not always true. Anybody can put something on Amazon and call it a certain brand. However, in this case I got lucky Bosch does have an official Amazon store front and I bought from that front. Now, Motorcraft on the other hand… it does not have an official storefront. Instead Amazon groups all “Motorcraft” branded parts together. All the Motorcraft parts on Amazon I’ve seen are counterfeit.

I put a rockauto closeout special on my B2....no issue

The main thing to look at with Amazon is not the seller, but the shipper.

If the seller is selling legitimate parts, and they are shipped by the seller. You get the real parts.

If it’s shipped by Amazon, then you get whatever is in the bucket. Could be a mix of rear and counter fit parts mixed together.
