The NGK direct-fit oxygen sensor for Mitsubishi Galant (1999) installs in place of the OEM sensor to supply continuous closed-loop air-fuel feedback to the engine control unit, helping preserve engine efficiency, fuel economy and emissions performance. Developed with NTK sensor expertise, the unit uses an advanced ceramic element and a 3-stage contaminant-resistant plasma jet plus deposit-trap overcoat to protect the sensor from poisoning and improve durability.
