Very good quality
My check engine light was on and of course I needed a echeck so I scanned the light and I needed an o2 but didn’t want to break the bank. So I bought this product. First off the quality was literally like oem quality. It fit right up to my car very well. I turned my car on after installing and the check engine light went away. Very good replacement part for a great price. My car was running way better after I installed it. Definitely recommend.

Worked as expected
Just so you know, this item does not include the Christmas tree plastic fastener. You will likely break the old one after removing.

Failed after 2 weeks
Installation was a breeze but it failed after less than 2 weeks. Had to buy a different one.

Perfect
Fixed my 2014 Chevy Spark with no problem. Great quality. Dealer said only AC Delco would work because it's a GM part. BS....
