O2 Sensor replacement part - NTK or Bosch?

[jamespwsullivan]

So in the Renix world there seems to be some opinions about which brand of O2 sensor is the best (or the only) choice.  I 'm trying to eliminate all possible sources of problems, and since the O2 sensor is a critical part of Renix, if I have to replace it, I'd like to know if there is an overriding opinion of one being different or better than the other and why.

Thanks

So I have actually purchased the Bosch O2 Sensor and plan to have it put in tomorrow actually along with some other things. I got it because it had a "red heart" beside is which means I assume best seller. Best seller means good part? And because I've also heard of Bosch before. I can't for sure say which one is better I just went off of the red heart beside it and the name I recognized and i do have the part on hand ready to be installed. Some other guys on here I know would know!

I have the BOSCH. Don't have a REM to verify how it's working.

 

According to NickInTime:

 

GOOD:
– NTK / NOS Mopar / ACdelco 23553: Highly recommend for it’s nice swing and more forgiving range.
BAD:
– Bosch 12009 NOT RECOMMENDED for lack luster swing, occasionally not moving at all, and having a harder time holding closed loop.

I have a Bosch, seems to work well, definitely noticed an improvement in performance compared to the 250k mile stock one that was in mine.  I'm interested to see what the REM says when it shows up.

My opinion is NOS Mopar. I had Bosch in the past and they worked great but it seems all manufactures have changed their design. They used to have white ceramic bodies with three wires coming out to the three pin connector, now all seem to have metal bodies with four wires going to the three pin connector. All the recent ones I tested, Bosch, NTK, Omix do not have the correct resistance between A&B, 4 ohms but spec is 5-7 ohms and did not cycle properly based on the REM. See this post

Bosch, NTK, Autozone, Chinese, doesn't matter. They all use the same metal bodied sensor that isn't supposed to be for the Renix, but it kinda halfassed fits the specs on paper. None of the ones you see advertised as a ceramic body will actually be one unless you find a NOS sensor. I used a AEM wideband and it's been working great all year and across the country.

 

It's value engineering at its worst. There aren't enough of our trucks or vehicles with similar EFI systems around anymore, so they try to buy one sensor, and sell adapted versions that can "fit" multiple vehicles, but at a loss of performance. NTK held out the longest, but they probably ran out of an internal component that went EOL years ago.

NTK is what I run for any sensors if it’s available. A nos sensor is nice if available and in good shape.

I bought a NOS sensor from a dealer. Came in a 90’s Mopar box. O2 was metal bodied and stamped with NTK on it. I do also have NOS O2’s in AMC packaging with ceramic and those are labeled with autolite on the ceramic base.

Thanks everyone.  Good info.  NTK's site says this:

NTK 23553 OE Identical Oxygen Sensor

That strongly implies that it meets OE specs.  Of course, one must trust what they say...

I'd still like to hear other experience agreeing with (or not) what's been said.
