The parts fit great on my 2004 Chevy Colorado Z71 LS. I'm glad I was able to get them for such a good price! The upstream sensor was about as bad as the downstream sensor. I used an impact wrench and it took out the old rusted in downstream sensor with ease. I highly recommend these parts

This purchase fixed my frequent error code and was reasonably easy. This is a very inexpensive fix that can save hundreds of dollars later. I suggest watching some tube videos to understand repair and tools needed. The sensor near catalytic converter or down stream sensor was not easy to remove. Cutting the wire and using standard tools helped remove it. A specialty tool it needed to tighten and fit over wire on sensors. It’s a sub 10 tool and can be purchased at Amazon also.

The units arrived quickly and well packaged. I already know that installation is not easy but won't know if they're any good or not until after I've driven the car a few thousand miles.

This was easy to install and helped improve mileage. Cost way less than an auto parts store.
