A better product than others from Amazon
Replaced all four O2 sensors last year with a cheaper brand in a 2009 Chevy Traverse. Less than a year later and a total of 3 have already failed. Not all at once but one failure about every three months. Purchased this A-premium brand to replace all the replacements, and they’ve been working great. You can tell the quality is substantially better just in the way the wires are protected at the sensor base.

Did not last long only lasted about a month and a half
Purchased a oxygen sensor, from A-premium April 3! And today is may 12th and it gave a p0161 code on my 2011 traverse.. there’s no warranty!!! And it’s past the 30 day window with Amazon.. I seriously hate just throwing out money like a fool.

It fits perfect
I used this to pass my emissions test to get my license plates my censor had went out and the check engine light was on and wouldn’t go off so once I ordered this and replaced it the light went off and now my automatic starter is working again!!!

Ad was misleading, who's only downstreams, not in upstream.
Their ad said it was a upstream and a downstream. Unfortunately, the upstream is a 4 wire, and the downstream is the 4 wire, but one square the other one's triangles on the plug in. So I had to go to autozone and buy one. It doubled the price cause I needed it right now. Kind of disappointing.
