The NGK direct-fit oxygen sensor for Chevrolet Malibu (1997–2003) replaces the factory sensor to provide continuous closed-loop air-fuel feedback to the engine control unit, supporting accurate mixture control, fuel efficiency and emissions performance. Backed by NTK OEM sensor expertise, the unit employs an advanced ceramic element protected by a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to reduce element poisoning and enhance durability in service.
