The NGK direct-fit oxygen sensor for Buick Encore (2013–2016) replaces the factory unit and supplies continuous closed-loop feedback to the engine control unit to support correct air-fuel mixture, fuel economy and emissions monitoring. Built with state-of-the-art ceramic sensor technology and a 3-stage contaminant-resistant plasma jet plus deposit-trap overcoat, the element is protected from poisoning to enhance durability and OE-level performance.
