So my front O2 sensor has chucked it and i have to replace it so mazda canada can do warranty work on my cat.so looking for a new one i came across Walker Products OEM replacement O2 Sensors.

http://oxygensensors.com/catalog.php...lication=M%2FT

They are way cheaper than stock but was wondering if anyone has used these ones or any other kinds.

Thanks

 

Only use OEM.

 

I recently replaced my rear oxygen sensor with the Bosch universal. Found it at the local PepBoys for $68, with a lifetime limited warranty. Had to splice 4 wires with the plug from the old one, but paid $110 less than the one with the OEM connecor from the same brand.

No CEL or any issues whatsoever afterwards, so I would recommend this.

 

Just don't try that with the front one

 

Replaced my sensor with a Bosch drop in replacement. That was like a year and a half ago..still works great.

Let me try and find the receipt so I can give you a part # and what I paid for it

Edit: It was 193 dollars shipped, Bosch
Part #: W0133-1813474

No wire splicing, threaded in and connected up like a champ. Verified with my accessport after install.

 

Your not gonna have a problem with it. It's always the perfect fit.
