Which O2 Sensors would you buy?

[badstang123]

I've been coming up with some lean codes (172, 176, 181, 189 all in continuous memory) and I know that the O2's haven't been replaced since I've had the car (Just over 80,000 miles) so I figured it would be a good idea to replace them. If you were putting them on your car which one's would you buy?

I was told by their marketing guy that Walker actually buys their bulk sensors from Denso then they put their own wiring on them. So there really is no difference. I have the Walker sensors and they work fine. I even have a wideband to make sure the computer is able to adjust and keep the A/F ratio in range. So far so good.

I've heard that either Bosch or OEM units are the ones to go with. The rest seem to fail.

Well...I don't think I could possibly go against that many similar opinions. I'll fork out a few more $$$ for the bosch ones from the local auto part store.

And I think it is really funny that even when I called Ford they seem to think there are four O2 sensors

I got them in. I don't think it made any power difference but it seems to run smoother. I also had this weird flat spot in power on part throttle and it seems to have helped that. We'll see how she does over the next week or so as the computer adjusts.

And yes I got the bosch ones.
