Replacement O2 Sensors?

[EvanH]

Its about time to replace my O2 sensors. What brand do you recommend? A lot of aftermarket wide bands are Bosch. Are they good for narrow band?

I used a Bosch, and it was reading a bit low after about nine months, but I had a failed factory one at the same time. I replaced the Bosch with a Bosch, and the factory one with a Denso. Both worked perfectly after that. The Denso seemed to be built "better" but the "OEM fit" cable wasn't quite OEM fit, which is where the Bosch was good. Honestly, I doubt it matters, if it fails, it'll likely fail quickly (within warranty).

What wasn't quite so "OEM Fit"?

The cable wasn't really long enough. It fit, but it was tighter than I would have liked by about an inch or so. The Denso also didn't come with the threads pre-anti seized, it had a little tube to cut open and slather on though, IIRC.
