Hey everyone, need some opinions/input. My '96 needs front O2s.
I see all sorts of options here:
Universals
-Bosch
-Denso
-?
Direct Fit
- Denso
- Bosch
- Walker
I have the cash for the pair of Denso direct fits, but will any of the others work well? I can get two direct fit Walkers for about $10 more than ONE Denso direct fit.

Quality quality quality...
The Denso stuff is better quality. Does that mean that the Walker brand will be crap in a month, probably not, but, I will guarantee the Denso's will be more accurate, longer... Same goes for Bosch - Bosch is quality, OE stuff... I haven't even heard of Walker o2 sensors and I work at a repair shop...
The only difference between direct fit and universal is that direct fit already have the right pigtail on them, whereas universal, you have to wire yourself...

In the RX300 forum, we have some O2 sensor issues and I always recommend to stick with the Denso. I remember a few people reporting issues with the RX300 with the Bosch, but that may be something endemic to our engine/ECM group.
My uncle has a garage and he has used the Bosch without issue on European vehicles, but the Japanese, he sticks with Denso.

Basically what I figured. I can repair anything on my fleet, so I'm not scared to do wiring... but my concern about the "universal" units durability over time.
I plan to solder them into place, not crimp. But can these hold up to 70-100k miles of use with extreme heat and still accurately read my A/F?
Not interested in doing something half assed.

104 unleaded won't do a damned thing to O2 sensors.
Just wondering who's had long term universals installed...

and of course so long as the wiring is done properly, there will be no difference in reliability...

leaded stuff kills o2 sensors fast, especially when that's all you use... however, if you use leaded gas just every once in a while, and normal gas the rest of the time, the standard gas tends to clean the o2 sensor to some degree...
I've seen 100% dead (from leaded gas) o2 sensors start working after some hard runs with standard unleaded... granted they die quickly when the leaded goes back in, but, it's definitely interesting...

f- that $70 difference...
what kind of prices have you found for the o2 sensors??? I show fronts and rears, rears being quite a bit more expensive... which ones do you need?
