Bosch O2 vs other brands: Is another reputable brand like a Walker O2 sensor an acceptable OE replacement?

I’ve seen posts that indicate Bosch only, and others that say a new O2 is better than an old regardless of brand.

Does anyone have personal experience they can share to help clear things up? Thanks!

 

I think walker has a good name around here.
rock auto has the walker for $35 and bosh for $57 Canadian. Dirt cheap

 

Walker, Denso, NTK, and even Delphi have worked well for me besides Bosch.

 

We say Bosch-only for MAF sensors and CKP sensors, but other brand O2 sensors have been okay for many. I've had a handful of Bosch O2s that were bad out of the box. Others haver reported the same. Walkers get a lot of praise.

 

Awesome info. I figured walker had a pretty good reputation from what I can tell. I’m going with the Walkers. Thanks for the feedback!

 

My truck only likes the O2 sensors that come from the factory. I have tried aftermarket from Atlantic British and it immediately threw an O2 code for both rear sensors. An expensive phone call later, the factory sensors took care of the issue

 

NTK #25623 UP & #25624 DOWN or Walker #350-34462 UP & #350-34188 DOWN.
