The NGK direct-fit oxygen sensor for Mitsubishi Lancer (2004–2006) returns OE-level oxygen sensing to the on-board diagnostic system so the ECU can control air–fuel ratio, support fuel economy and limit emissions. Made by NTK, the sensor uses a 3-stage contaminant-resistant ceramic element plus a deposit-trap overcoat to protect against poisoning and increase resistance to failure while matching OE fit and function.
