sensor and toll
March 14, 2017
All arrived ahead of schedule, the sensor was packed in with brakes and rotors and arrived broken. took a few extra days to get a replacement. The sensor tool was useless for the removal. Due o the opening the socket kept spreading so for the removal it was no good.
Great part

O2 sensor
June 2, 2018
First purchase for auto parts on line and the O2 sensor works awsome. Engine light is off and stayed off. My mileage has gone from 21 average to 28 on my 2006 Chevy Cobalt.
Works good

O2 sensor was exact fit, and all the engine codes cleared
Did the job
November 26, 2018
I was not able to use the tool for removal, it kept slipping off but I got it off with a pipe wrench and used the tool to install the new one and it worked just fine. My engine light does not come on any more and my truck runs great now.
Good Product, Would Order Again

I installed this on a 2004 Silverado 1500 5.3L, upstream. The product fit perfect and functions as it should. I no longer have a check engine light illuminated on my dash. The only reason I would not review this product as 5-star is because the included socked was a bit flimsy. My sensor was stuck pretty good, and this socket would flex when I applied force, and rotate around the points on the sensor. I ended up buying a different style O2 socket to complete the job. I would still buy this product again, and now I have this handy socket for "less stuck" O2 sensors.
No problem

I needed to replace to O2 sensor on my wife's truck. This one arrived quickly (even during the pandemic). The part worked as advertised and even came with the required tool. It was much cheaper than any of the local parts stores.

This O2 sensor says upstream , are the upstream and downstream sensors the same ? I intend to replace all sensors and wondering if this would work for all the sensors ?
April 20, 2021
Matthew G
Some vehicles have the same upstream and downstream sensors and others will be separate parts. You should be able to determine the fit through our vehicle fit list.
