NGK Lexus SC400 1995-1992 Direct Fit Oxygen Sensor

This is a direct fit oxygen sensor from NGK for your 1992-1995 Lexus SC400. Oxygen sensors are a key part of your car's onboard diagnostic system, helping to keep the engine running at its best. They provide feedback to the engine control unit (ECU) to manage the air-fuel mixture, which is important for getting good gas mileage and keeping emissions in check. If the sensor isn't working right, it can also alert you to potential issues with fuel delivery or the catalytic converter.

NGK, a major supplier of original equipment sensors, builds these with an advanced ceramic sensor element. This element includes a special coating that acts as a trap for contaminants and a plasma jet, which helps protect it from poisoning. This construction is designed to improve resistance to failure and ensure consistent performance over time. Because NGK is involved in the development process with OEM manufacturers, you can trust their sensor technology.
