Review on 🔌 GM Genuine Parts 213-968: Black Heated Oxygen Sensor for Reliable Performance by Corey Slivinsky

Very concerned that the item was unsealed and arrived WITHOUT identifying instructions. To find out if sensor 02 was upstream or downstream. As in an auto parts store, such an item is usually sealed and comes with instructions. I was concerned that this part had already been used and was being returned. if you put the wrong or used 02 sensor on the wrong end of the exhaust pipe. Then it is likely that the part is NOT working properly and the check engine light is NOT going out due to the trouble code. Maybe it's because the part was misused or misused. FYI: If you're buying from online retailers, make sure it's new if you're expecting a new part. And in the original branded packaging, sealed and with instructions included. FYI: Don't forget to cross the part number to match your vehicle. before you order and after you receive it. There's nothing worse than receiving a part and then installing it, only to find out later that it was wrong. So now you have doubled your work and time. And the hassle of shipping and trying to get your hard-earned money back. Attention buyers!
