Review on ACDelco 213 4537 Original Equipment Heated by Tim Thomason

Ordered for my 2014 Equinox and there is absolutely no way it was a new upstream O2 sensor. The package arrived with the top O2 sensor loosely packed in a standard GM box. The threads had an anti-seize coating with a damaged metal seal (probably from a previous attempt at installation). There's a human hair stuck in the wiring harness (I swear to god). I didn't even bother installing this as it's very difficult to reach the O2 sensor upstream of my car. This item was claimed to be sold by Revain but I just can't believe it as I can't remember the last time I had a problem with something that was Revain stock. If they're getting it from somewhere else, they need to talk to them because it's a very bad idea to pawn refurbished equipment as new for cars. I just go to an auto parts store to get a decent one to inspect and pay a premium.
