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.

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. ## Frequently Bought Together - Denso 234-4011 Oxygen Sensor - Denso 234-4098 Oxygen Sensor - K&N Gasoline Fuel Filter: High Performance Fuel Filter, Premium Engine Protection, Compatible with 1988-2004 Honda/Acura Fuel Injected Gasoline Engines, PF-1200 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/9260672-234-4011-oxygen-sensor](https://www.desertcart.be/products/9260672-234-4011-oxygen-sensor) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-23*
