NGK Geo Prizm 1992-1990 Direct Fit Oxygen Sensor

The advanced ceramic sensor element in this NGK oxygen sensor features a 3-stage contaminant-resistant plasma jet and deposit trap overcoat. This design helps protect the element from poisoning, which is crucial for maintaining optimal engine performance, maximizing fuel efficiency, and reducing harmful emissions. As a vital part of your vehicle's on-board diagnostic system, oxygen sensors provide constant feedback to the ECU, helping to control the air-fuel ratio and alert you to potential issues with fuel delivery or catalytic converter efficiency.

NTK, a ceramics company at its core, controls the ceramic element used in their oxygen sensors from the raw material all the way to the finished product. This allows for advanced technology and improved resistance to failure. This sensor is designed as a direct fit, meaning it's made to install easily onto your Geo Prizm or Toyota Corolla without modification.
