Passed smog test!
While everyone charges way too much these days for everything. Sometimes you get lucky, that's how I feel about this product. I'm so glad that I took a chance and gave it a shot. It Works 100 percent satisfied ššÆ

Half didn't fit my 02 Tahoe Z71, other half failed in two months
I should have just popped under my Tahoe to check first, but both the upstream and downstream sensors are the square plugs on my Tahoe, there are no rectangle ones. That's on me. But, at least I had two square ones from this order and I just ordered two more square ones from another vendor. Well, now the square plugs from this order died within two months of install. I will be avoiding this vendor in the future.

Replacing these yearly.
First set lasted just over a year. Never got a response from manufacturer regarding the warranty. Thankfully not too expensive to be replaced yearly, 4 of these cost what a brand name one from the local parts house cost.

Didn't work with GMC Sierra
I installed all 4 of these in my 1999 GMC Sierra 4.3l.Once installed I was getting a check engine light for P0134 and P0154. Neither of these codes where there before hand. Also the misfire the truck had got worse. I replaced the new O2 sensors with AC Delco brand sensors. Those codes went away as well as the misfire.

If you want headaches from Oxygen sensors buy these
I ended up having to buy Bosch oxygen sensors from Oriellys auto parts .All 4 upstream an downstream were as useless as a bucket under a bull .If you catch my drift. Completely trash Yes they look nice when they come out of the box but are better being put straight in the trash can . This taught me a good lesson again to go straight to the dealership an buy OEM from Chevrolet .I didnt even care about sending them back to Amazon for my money back .Lesson well learned .
