Where to get Oxygen sensors
 

So I've tried looking everywhere from local to online. I either get find the wrong part, or the prices are ridiculously priced high. I was wondering where other members bought their O2 sensors? (for those who had to replace them) I need wideband, 4 wire, pre-cat O2 sensors btw. ANY help would be very much appreciated. Thanks in advance everyone! :tiphat:

No way you're going to get those for cheap. They're wideband sensors.

The only possibility is swapping in some generic Bosch wideband sensors, which are about $100/piece.

May I ask you what's wrong with yours? They're covered under the emissions warranty of your car, and ought to be replaced for free even if you have mods.

:iagree:

Did you try Courtesy Nissan?

How come you need to replace yours?

They're still over $300 a pop:

I thought he was looking for an O2 sensor, it's $145.

He's asking for the pre-cat wideband sensors, which are what I linked to. $330/piece. You linked the cheaper narrowband rear sensors.

I see. :tiphat:

They aren't cheap! $$$

get the walker brand o2 sensors off of oxygensensors.com they are they cheapest ones you will find and work. I have one on my car right now

Good advice! How are they different? Or are they just wholesaled out, rebranded OEM sensors?

Guessing the stock sensors themselves are actually Denso...

stock sensors are denso. And i did some research and generally walker just buys them from another manufacturer and just rebrands them. They look slightly different than the oem ones but have been working great so far.. no issues.

Thanks for the responses everyone! :D

@WarmAndSCSI
I had my stock headers removed to have my Stillen headers installed. We tried to transfer the stock O2 sensors to the aftermarket headers but we couldnt get them off. The mechanic basically forced them off and when he did get them, they were too screwed up to use.

yea thats what happend to me on one of the sensors.. just get the walker one from oxygensensors.com and it will work just fine without spending 800 bucks on 2 sensors.
