Description

The NGK 24543 is a direct-fit oxygen sensor designed for select Nissan Pathfinder and Infiniti QX4 models from 1996 to 2000. Oxygen sensors are crucial for the vehicle's diagnostic system, helping to maintain optimal engine performance, maximize fuel efficiency, and reduce emissions. This sensor provides feedback to the ECU to control the air-fuel ratio and alerts the OBDII system to potential fuel delivery or catalytic converter issues. It features an advanced ceramic sensor element with a three-stage contaminant-resistant coating to protect against element poisoning.
