The connector was grey instead of blue like the original, but seemed right other than that. The mpg dropped right after installing this sensor. I had installed a matching set of up/downstream. These really didn't last for me. ### ⭐ No good *by B***N on Reviewed in the United States on February 9, 2019* Replaced them both with this brand and mileage dropped ### ⭐⭐⭐⭐⭐ Works as intended. *by C***W on Reviewed in the United States on November 30, 2018* Works like intended. --- ## 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.com.kw/products/50738233-downstream-oxygen-o2-sensor-234-4370-sensor-2-replacement-focus](https://www.desertcart.com.kw/products/50738233-downstream-oxygen-o2-sensor-234-4370-sensor-2-replacement-focus) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-30*
