The NGK direct-fit oxygen sensor for Chevrolet Impala (2014–2016) supplies continuous closed-loop feedback to the engine control unit to help control air–fuel ratio, increase fuel efficiency and reduce emissions. Built with NTK ceramic sensor technology, the sensor features a 3-stage contaminant-resistant plasma-jet and deposit-trap overcoat that protects the ceramic element from poisoning and aligns with OE application development practices.
