The NGK direct-fit oxygen sensor for Acura CL (2001–2003) delivers continuous closed-loop air–fuel feedback to the ECU to support engine performance, fuel efficiency and emissions monitoring. Produced by NTK, the sensor uses precise ceramic element control and a 3-stage contaminant-resistant plasma jet with deposit-trap overcoat to reduce element poisoning and improve durability while aligning with OE application technology.
