Walker Products 350-34581 Oxygen Sensor, Original Equipment Replacement O2 Sensor,

Got code, replaced just this one, and passed emissions. Looks different than Oem one. Used a line wrench. Easy! 150k miles on my 08 silverado 1500. Walker is on left, Oem on right.

Sensor was great purchase for bad sensor,worked like advertised

O2 sensor was a perfect fit. The hardest part was convincing myself that I could do it. It was simple. I'm going to make another purchase and replace the other O2 sensor.

I bought this for my 13 Tahoe with the 5.3. had some codes for slow response for the Bank 1 O2 sensor, installed this sensor and it cured the light right away, Went ahead and got a second to install on Bank 2.

Got item with torn box from Amazon warehouse. Exact fit. Have put 4000 mile on sensor and only had 1 code when first installed. No codes since. Seems a better sensor than chinese cheap sensors, which set a plethora of codes. Recommend.

These were perfect replacements for my Yukon- we were getting a rich/lean code occasionally on the truck which could be an 02 sensor or the cats, rather than pay a diagnostic fee we just replaced both front 02 (2 were cheaper than our diag fee at the local shops) and it resolved the issue. I would buy the offset O2 sensor socket- we needed it, but it depends on your application.

Product matches Perfect to OEM parts super easy to install, heat motor for one minute not too long or it’s too hot to work but just enough heat to help bust the old sensor loose. Restored all lost power and eliminated rough idle and improved fuel efficiency.

So far so good
