I'm looking to buy the rear o2 sensor thats on the catalytic converter for a '95 Maxima. Can anyone refer me to a cheap websites? What about ebay o2 sensor, like this one below?

I got a direct fit density from rockauto.com for $50 shipped.

 

Sorry, Denso.

 

Good find on the ebay one. Good price! I paid 60 for mine cause at the time all ebay ones were about the same and i didnt want to wait for shipping. I'd think that like a lot of things, if it fits, it'll work and since thats OEM you should be all set.

Edit: If you've never done an O2 sensor, spray the hell outta it with PB Blast and let it sit for a while before you attempt to get it out. I figured that out the hard way when i did mine.

 

Denso FTW! I'm using one as well.
