The NGK direct-fit oxygen sensor for Chevrolet Optra (2004–2005) delivers closed-loop exhaust feedback to the ECU to aid air–fuel ratio control, fuel economy and emissions monitoring. NTK's ceramic sensor engineering incorporates a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to defend the element against poisoning, and the design is developed with OEM manufacturers for OE-compatible durability.
