I've heard bad things about Bosch. Zero personal experience with them, but I've been disappointed in other Bosch products and Bosch-owned companies (OTC Tools, for example), so I avoid them like the Plague.

No real opinion on other brands. I'm in the process of cramming four sensors into my '97; I bought Densos this time.

I've used Delco O2 sensors and been satisfied. Same with NGK.

The "speed" of the O2 sensor probably has more to do with it's age and mileage than with the brand. Kinda like batteries--Bunny or Coppertop, doesn't make any difference, it's the base chemistry that sets batteries apart (zinc-carbon, "alkaline", and the newer, more-expensive formulations) not the manfuacturer.

Yes, they will get "lazy" with age. If they get contaminated with anti-seize or silicone, throw them away. I use heated ACDelco NB sensors, but I did go with a Bosch WB O2 in an Innovate kit for tuning, still seems to be working OK.

Had a denso and it was junk. Lasted for 3 months! I use AC Delco for most stuff these days.

I have also heard more bad about Bosch O2 sensors.

Ironic, I replaced both O2 sensors 2 years ago with Delco. One failed in less than a year, the other I just replaced tonight. Delco has a ****** design where the ground is soldered to a lug that's spot welded to the sensor body which failed on the one sensor and just fell off.

I would think either would be fine.

May want to consider swapping to a heated o2 sensor, as I think a 94 was still non heated.

My 94 is the heated one in the crossover.,Ordered the denso and its working great for now fast counts so far so good but only been on 1 day.
