Less than a year later and a total of 3 have already failed. Not all at once but one failure about every three months. Purchased this A-premium brand to replace all the replacements, and they’ve been working great. You can tell the quality is substantially better just in the way the wires are protected at the sensor base. Review: High quality replacement part - High quality replacement equal to or exceeding manufacturers specifications. Highly recommended product with affordable price tag. Perfect way to offset costly routine maintenance costs. ## Features - 🍒Compatible with Buick Enclave 2009-2011; LaCrosse 2005-2014; Rendezvous 2005-2006; Cadillac SRX 2010-2014; XLR 2004-2005 - 🍒Compatible with GMC Acadia 2009-2011; Terrain 2010-2014; Saturn Outlook 2009-2010; Cadillac CTS 2004; ELR 2014; - 🍒Compatible with Chevrolet Captiva Sport 2012; Equinox 2010-2014; Impala 2012-2013; Traverse 2009-2011; Volt 2011-2014; Impala Limited 2014 - 🍒Position: Upstream and Downstream - 🍒Detect oxygen content in the exhaust gases to optimize emissions and fuel economy ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07CQNBRWH | | Best Sellers Rank | #57,919 in Automotive ( See Top 100 in Automotive ) #66 in Automotive Replacement Oxygen Sensors | | Brand | A-Premium | | Brand Name | A-Premium | | Customer Reviews | 4.3 out of 5 stars 431 Reviews | | Item Weight | 0.14 kg | | Manufacturer | PremiumpartsWhosale | | Material | Zirconia, Stainless Steel | | Material Type | Zirconia, Stainless Steel | | Model | 12584050 | | Mounting Type | Flange Mount | | Number of Items | 1 | | Number of Packs | 1 | | Output Type | electrical signal | | Part Interchange Info | 250-24649 | | Part Number | OS046C | | Specific Uses For Product | Oxygen Sensor | | Style | Modern | | Style Name | Modern | | Upper Temperature Rating | 1650 °F | | Warranty Description | One Year Unlimited Mileage Quality Guarantee. | ## Images ![A-Premium Upstream and Downstream O2 Oxygen Sensor - Image 1](https://m.media-amazon.com/images/I/61z+hCa-2YL.jpg) ![A-Premium Upstream and Downstream O2 Oxygen Sensor - Image 2](https://m.media-amazon.com/images/I/71XVNqI4jgL.jpg) ![A-Premium Upstream and Downstream O2 Oxygen Sensor - Image 3](https://m.media-amazon.com/images/I/61Jc7GprkbL.jpg) ![A-Premium Upstream and Downstream O2 Oxygen Sensor - Image 4](https://m.media-amazon.com/images/I/71BjeYL66IL.jpg) ![A-Premium Upstream and Downstream O2 Oxygen Sensor - Image 5](https://m.media-amazon.com/images/I/61tT99d+dNL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ A better product than others from Amazon *by E***S on August 22, 2025* Replaced all four O2 sensors last year with a cheaper brand in a 2009 Chevy Traverse.
