The NGK direct-fit oxygen sensor for Chevrolet Cavalier (1998–2001) replaces the original sensor to provide continuous closed-loop air-fuel feedback to the engine control unit, helping preserve engine response, fuel economy and emissions performance. Drawing on NTK's OEM sensor knowledge, the design uses an advanced ceramic sensing element with a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to protect against poisoning and enhance service life.
