I got my first replacement o2 sensors from Rock Auto in Feb of 2020, they were the economy models $51.79 each. They lasted just until the warranty ran out on them and now I got a service engine light.
ULTRA-POWER 2349038 {#226931AA0A, 226938W90A} (Economy)
UPSTREAM LEFT; UPSTREAM RIGHT.
Do you prefer a particular brand or part number, and do you get better mileage with a particular brand?
Also, correct me if I am wrong, the upstream sensors are the O2, and the down stream sensors are for air/fuel monitor?
At this point, I am likely going to replace them with a slightly more expensive unit, also from Ultra Power. I don't see the sense in spending 2x or 3x more money on a name brand if the mileage will remain basically the same.
Maybe some of you have better input on this topic than I have, which is why I am asking your opinions.
