O2 sensor options

[RobE30]

I'm going to be buying a replacement O2 sensor for my 87 325is soon. Does brand make that big of a difference? Denso, Bosch etc? I was not planning on getting a "universal" fit w/ no plug fwiw

If the sensor is an OE equivalent exact fit part, it shouldn't matter what brand the sensor is, but the OE part is Bosch.

Ok thanks. I know w/ Toyota's (at least what the yotaheads say) if you run any O2 sensor other than Denso (OE), you'll have problems.

you want a 4 wire bosch narrowband sensor. I don't know if other brands will work but I suspect not. Otherwise it doesn't matter much.

On Toyota's and with my years of experience with them, yes. They have to be at least OE-equivilant (Denso/Bosch - doesn't matter) and not ghetto-rigged.
