Are there any specific brands of O2 sensors that guys are running? I have to replace one, so I'll do both, but these sensors aren't very old, I didn't know if any one brand is better than the next. Thanks

 

AC Delco #AFS75

 

Ok, thanks

 

IMO, Denso. Had a pair of Delcos fail after a thousand miles, and IIRC have heard grumblings about Bosch.

 

Ok, thanks

 

while any part/brand can fail...The AC Delco ones are what is regarded as the "right" brand.

I have also heard negative on Bosh, never used them

never used Denso either but SS RRR states he is happy with those.

If you have failing 02's within not much mileage as a pattern....you should confirm you don't have a issue "causing" that. vacuum and pre 02 exhaust leaks are two major reasons 02's fail as they read lean from the unmetered air and PCM dumps fuel making a rich condition which takes a toll on 02's

 

I would also say AC Delco, but I have no experience with any other brands. I will say that I've read of lots of bad experiences with Bosch.

 

Ok, thanks guys. Thanks ******, I'll have to go back and make sure all of my exhaust clamps are tight.

 

Ive seen more success with the Delco's, What I have seen in the Bosch, is that they are lazy at start up then eventually will / might start working correctly.

 

All Narrowbands are the same

I went once with the owner of a local performance shop ("Force Fuel Injection") to a large warehouse full of bins of car parts. Just bins and bins of every and any car part that you could put in a bin I guess, injectors for example. So they had this huge bin of O2 sensors. You are allowed to buy like 80 of them for $3 each or something. The point is, we used them in every stand-alone application that came through the shop, every V8, V6, whatever from wherever, it got one of these $3 sensors and worked great. When I need one now I just start price checking the local auto-store Oxygen sensors until the guy either gives me one to get rid of me or I find a very cheap $5-$12 sensor, and use it!

 

I put Densos in when I did my headers 7 years ago, still working fine.

 

Thanks for all the comments guys.

 

The last time I bought AC Delco, I got a Denso sensor in their box. Now I just buy Denso, because they're cheaper.

 

Ok, cool

 

Hi N2O, I fit the NTK "Hot Start" EGO sensor with normal life 2X that of Bosch.
This sensor is sold by NGK
There are TWO White Wires (Heater)
One Gray, sensor Ground
One Black, Output to PCM

The color code is different from the GM fitted sensor. (Bosch & NTK are the same)

The Bosch (late) EGO sensor works well with the same calibration.
The AFS75 sensor I have tested with DIFFERENT Calibration REQUIRED and shorter life than Bosch.
I do not know who manufactures this sensor, I believe it is Denso ?
The China EGO sensors FAIL, as my testing found when I helped Walker with their sensor program.
THEY GAVE UP trying to use China Sensors.

AS SEEN by ALL "read Kings tech" then do the opposite.

I sell EGO sensors AND have done so for Thirty Two Years.

Thanks for the info.

 

A narrowband is a band-aid for sheep to drive a car. If you are into performance, you should also be interested in how the computer works and tunes the engine. If that is the case, you buy a wideband, and get rid of the narrowband.

The only thing I "said" with my "long post" was to buy the cheapest sensor to save your $$$. Thats all I ever say, its my online trend of trying to save people money. No, it won't be the highest quality sensor, maybe not. But it does come out of an OEM quality NTK box from your local auto-store (or whatever they carry that is like an OEM sensor) nobody said anything about chinese sensors etc... Just the fact they all work the same and that any sensor will work in place of any other sensor when concerning 99% of narrowbands in the world for 99.9% of cars in the world. I don't get paying $80 or $125 for a $3 sensor. The bulk sensors for $3 were OEM NTK sensors btw. This was 15~ years ago before chinese copies of **** was being made rampant.

 

That's just silly.

Along with this.....trying to save people money...my backside. Tells the OP to buy a $3 sensor, then recommends to re-engineer the car to try and make a wideband work with the stock PCM. Nothing but straight up trolling.

I'm sure there is some truth with common suppliers to the OEM's, but the advice is just bad all the way around.

 

It's ways of thinking by "best laziest" opinion after years of experience. best engineer is laziest engineer, he only does minimum amount of positive work to get absolute job done.

For example, I just put 5.3L into nissan car. It will never get a narrowband because open loop is tuned precisely for my climate. Since I am not Chevrolet, I don't need to build 5,258,424 of the same exact vehicle and ship to 132 different countries, with a system compatible for all of them. I just need to focus on my 1 climate, or wherever I know I will be. Open loop is superior in this situation because we can target 15.2:15.5:1 in my country/climate based on what fuel is available is possible, achieving greater economy than when using a narrowband. This is advanced tuning topics, we can calculate the theoretical maximum amount of work an engine can do based on a given mass of some specific fuel, regardless of the air fuel ratio there is still some max work possible and it can be derived.

 

Again, you miss the point. The point is all Narrowbands are the same. You can walk around any junkyard in the world and put any number of random sensors into a bag and use any of them. That makes them essentially free. You save money now, cause I show you that


... thats if you even wanted one. I already show you, don't even want one. Save that tree fiddy for lochness monster
