The NGK direct-fit oxygen sensor for Chevrolet Astro (1998–1999) installs in place of the original sensor to continuously feed closed-loop air-fuel data to the engine control unit, helping sustain efficient combustion, fuel economy and emissions control. Leveraging NTK sensor development, the unit employs an advanced ceramic element with a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to protect the sensing element from poisoning and extend reliability.
