The NGK direct-fit oxygen sensor for Chevrolet Astro (1996–1997) replaces the original unit to offer continuous closed-loop air-fuel feedback to the engine control unit, helping preserve proper mixture control, fuel economy and emissions monitoring. Using NTK sensor development experience, the design includes an advanced ceramic sensing element with a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to resist element poisoning and improve long-term reliability.
