Quality worth the price
The genuine article in the box, assembled in america. Ready to go, easy to install. Connectors fit perfectly (they each have an opposite end so you can't plug in the 2 sensors in the wrong plugs). Functioning perfectly. Comes with threads pre-treated with anti seize compound plus a small tube of extra compound. Do not use more than the smallest amount if you add from the tube. There is enough there to do probably 20 times. There are cheaper units, but this is very high quality and should last a very long time.

Great replacement sensor!
This part went in easily on my 2005 Honda CR-V. Unhooked my battery for the duration of the replacement and after hooking the battery cable back on, my check engine light was off and did not turn back on again. My car is now running great again with previous good gas mileage. I read up on air/fuel (aka oxygen) sensors before I purchased one and read that it is extremely important to buy either an expensive OEM sensor or a Denso brand one. Apparently other manufactured sensors are not wired properly and will not work.

Don’t cheap out on O2 sensors
On the pricey side but don’t cheap out and when buying O2 sensors because you will be buying it twice. Worked perfected and check engine light has been off. Passed smog

Perfect fit. Engine light came off and stayed off
Easy install.works great. I first tried a cheep one from ebay. Total trash. Engine light came on within 30 seconds of starting car after clearing engine code. Installed this one..have put almost 1000 miles on it, not engine light. Dont waste your time with cheep ones. Get the oem
