I use Bosch on everything, except Toyota's where I use Denso. Having said that, I would probably be OK using Bosch in a Toyota, especially if replacing both and the Denso price was too high for me. I have a Bosch O2 sensor on my 1995 Escort that still works at around 145K - 150K miles.
 
What's wrong with Bosch? They're a massive OEM supplier for oxygen sensors. Is this another one of those unfounded "only use Japanese parts in Japanese cars" things?

Denso, NTK, and Bosch are all comparable.
 
If you're replacing it/them to fight a lean code then more research might be needed. It's common for a lean code in the winter with a 04 Matrix/Vibe/Corolla.

And why is that? This is the kind of thing I read on car sites all the time and nobody says why.

My reportedly 'picky' Subaru is running just fine on its two Bosch O2 sensors.
 
For Toy cars: I always get the OE O2 sensor (upstream; for downstream, any major Japanese OEM such as Denso, NTK, etc. will do justice).

I only stick to Bosch O2 sensors when servicing OBD-1 automobiles, and/or European varieties that comes stock with Bosch to begin with.

Nothing wrong when Bosch O2 sensors for OBD-II automobiles, just subjective preferences...

Q.
 
Toyota owns the majority of NipponDenso,so its no surprise most Toyotas are loaded with ND stuff.

I use NTK and Denso but also Walker.
I believe they are Denso units just wired by Walker, the quality is very good and the wiring is the same color, connector and quality as OEM.

I have had them running for a few years and no troubles even with Infiniti wide bands which were much cheaper than OEM. I highly recommend them.
 
Dealer.
Denso may be the OE supplier, but their aftermarket and OE lines are not the same. They may look/smell/feel the same, but it is impossible to verify that they are.
 
If you plan on ordering through Rock Auto, avoid the AWPI ones. I tried them in the Audi and they were both junk straight out of the box.

I went with Delphi and had no problems with them.
 
Hello, I am under the impression BOSCH made mostly "universal fit" sensors.
Many on the Volvo board I read claim that BOSCH sensors still generated codes and that DENSO was the OE manufacturer.
The DENSO I bought for my "picky" Volvo has worked perfectly for months so far.
The DENSO I need for an Acura's upstream sensor is $152 from RockAuto.
Pep Boys has a BOSCH listing for $250.
Retail craziness aside, I'm going with the DENSO.

I freely admit I know nothing. Kira
 
IMHO it's not Bosch or any particular brand that can cause problems, it's that using the original brand assures that the new sensor will connect properly and put out the right signal, especially with AFR sensors.
 
Sort of along the same thoughts that Quest has.

On my Audi V6 engines..I use a Bosch sensors upstream and Denso sensors downstream. Over time/miles the Bosch sensors get sluggish (not defective..just slow) in response time, the Denso sensors stay very alert and responsive over many miles.looking at the VAGcom.. The combination of mixed O2 brands seems to keep the German engine control unit measuring differentials, the standards set very tight by Audi, happy and the dreaded CEL from lighting up on older Audi cars.
 
I always try to use the factory brand on O2 sensors as they seem to work the best. Years ago I bought a new 93 Chevy S-10 4x4 with the 4.3L/auto and when I went to change out the factory O2 sensor, it was made by Bosch. that kind of surprised me as I thought it would be an AC-Delco.

Huh? That's a pretty wild claim to make.

Exactly. Some arbitrary rule gets invented and perpetuated, and there's no facts behind it, much like the "you can't switch to synthetic" phrase.

Between NTK, Bosch, and Denso, I would get whichever is cheapest.
