The NGK direct-fit oxygen sensor for Chevrolet Avalanche 2500 (2002) replaces the factory unit to supply continuous closed-loop air-fuel feedback to the engine control unit, helping maintain correct mixture control, fuel efficiency and emissions management. Built with NTK OEM sensor experience, this sensor uses an advanced ceramic element protected by a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to resist element poisoning and improve long-term durability.
