I pulled a code for one a few months ago. I didn't write down which exact one it was. I got my codes pulled again a month ago, it dissapeared. I did some searching and couldn't get a clear definite answer.

My question to the org is..Is there a sensor that usually goes out first and has a bigger impact on MPG opposed to the other 2? I'm fed spec, OBX headers to custom 2.5'' cattback, test pipe. Also,Is getting a known brand like Bosh the best choice or can I skimp out on a no name like I did on my knock sensor.

I'm going to order from RockAuto as they have the best prices I've seen so far. Thank you for your help.

the 1st two are for air/fuel mix so they would have the greatest impact. as for brands, i would stick to Bosch(i know but they invented o2 sensors) denso or NTK. Bosch is actually what comes stock. i have heard of people still having problems with cheap o2 and replacing others parts only to come back and put a good o2 in and fix the issue.

I went ahead and used the Bosch when I replaced mine. No problems so far after a couple years.

Bosch and Denso are very good. VisciousMo, the guys at Autozone near my apartment actually suggested the Densos. He had put those in his car and his daughter's. I think his daughter is rocking that crazy barbie Pink 4th gen Maxima you may have seen in town.

what code are you throwing? I have a P0420. On mine it's either a vacuum leak or failed cat.

People in the past have said o2's are part of the problem. But my shop says no...

So my question again is what do you have?

When I needed to replace my O2 sensors in my Pontiac and the wife's Subaru, NTK (NGK company) O2 sensors worked just fine, and were not very pricey either

I prefer the NTK as well because the sensor is a pretty simple device. Like they said the first 2 matter the most
