I've used the search tool for o2 sensor brand and got lots of threads about replacing them but not a favored brand.
I see the set of 4 at AB for a fairly reasonable price. Do they use Bosch, Walker, NTK?
Rockauto has them all and a set of 4 is about $30 or so bucks cheaper depending on brand.

Apologies is this has been covered but I couldn't find what I was looking for.

Thanks folks.

 

im not sure with the name with AB brand but they last very long and no faults upon installation. I had those before but unfortunately switched to bosch as many using them but they fail a lot. 3 to 4 in my experience. I have no choice at the moment coz they are still under warranty. I got a new o2 code at the moment but no time to switch or return one. So in my ecperience again, all failed fast. Few are out from box.

 

I got the walkers off of rock auto and no issues so far. Would use them again

 

Walker is the brand AB will recommend if you call them. They last way longer than the Bosch you get from Amazon!

 

D2's rolled off the factory floor with Bosch if I'm not mistaken. D1's were NTK's I think.

I've used Bosch with no issues as of yet on 6-8 D2's so far.

 

I've never had a problem with a NTK sensor. So it's NTK only for me. You can search the NGK/NTK catalog here > https://www.ngksparkplugs.com/

 

I decided to use walker after reading about all the out of the biz failures on the Bosche sensors.

Also got mine from rock auto and they are operating well thus far. About 5 months and no issues.

Have been using Bosch for 2 or 3 years, no issues.

 

Wow, good comments on almost all the brands but sounds like the Walkers are head by a nose.
Thanks for all your input.

 

Yeah, I've always thought it was best to go with the Bosch but I've had enough problems with them through the years that if and when (when really, I guess) one fails again I will try Walker.

Sometimes the Bosch have been bad out of the box and other times they just haven't lasted very long.
