easy to put in and good quality

Good product Great price. Seller was correct, check electric connection. My Chevy was changed mid production year. I have to buy this again, but way cheaper than through a Chevy Dealership.

Sensor functionality,Value for money,Ease of installation,fitness and sensor quality.

Bought these for a new engine change. Glad I didn’t throw away my old ones. This was junk from the first start. Engine ran fine. But I couldn’t clear the check engine light. I removed them after a dozen or more attempts of clearing the engine light. Put old ones back in and issue went away.

Excelente

They work really good BUT like my Chevy Silverado 2003 1500 4.3 L use four female connections , this package brings 2 males 2 females so u have to improvise and change 2 connectors from the old ones to the new ones , other than that they work great 👍

Installed for about 3 months and no issues

They fit right but they are a little different than the factory ones and they make my check engine light come on and stay on and the connection plugs were different I ended up buying more from auto parts I wish I could send them back and at least get credit for them
