Review: Best on the market - Excellent with zero issues!
Review: Worked perfectly in a 2000 Civic Si. Just buy it - no brainer.. - Update, 06/24/2022: ~10 years old and still passing emissions inspection.. Original Review: I didn't know Denso until I found out I needed a front O2 sensor. After being told by Honda that it would be $290.00 for the sensor and another $150.00 for labor, I did some research and found that Denso is a respected company in the Honda enthusiast community and an oem. I checked several online sources and a local chain. desertcart had it for about 10 bucks less on average (thanks desertcart). It even came with anti-seize paste. After having it installed (should have done it myself but had Honda do it for 150), the check engine light went out and all is well. It's too early to talk about long term performance but so far, so good. Great product, great price, great desertcart service. Happy customer.

### ⭐⭐⭐⭐⭐ Genuine Denso sensor,
*by A***X on April 24, 2020*

This was a "Sold By Amazon" purchase, not one from a third-party seller. It is a GENUINE Denso O2 sensor, not one of the many fake Denso bootleg sensors out there (this was confirmed with a representative at Denso USA). Correct upstream fitment for my 1999 Honda CR-V, with the correct connector already installed, and was completely plug & play. If you're having difficulty getting the connector of your old sensor to come apart, it may be because it's a fake Denso sensor; this was the case with the bad sensor I was replacing, and the connector of the Chinese fake wasn't molded quite dimensionally correct. Also, remember to disconnect the battery GROUND before and during installation.
