NGK Porsche 911 1994 Direct Fit Oxygen Sensor

The advanced ceramic sensor element in this NGK oxygen sensor is built with a 3-stage plasma jet and deposit trap overcoat. This design helps protect the element from contaminants, which can cause premature failure and affect performance. As a crucial part of your vehicle's on-board diagnostic system, oxygen sensors constantly send feedback to the ECU to help maintain the optimal air-fuel ratio, which in turn maximizes fuel efficiency and reduces harmful emissions. This sensor is designed to alert your OBDII system to potential issues with fuel delivery or the catalytic converter.

NTK, the world's largest supplier of OEM oxygen sensors, works closely with manufacturers from concept to production to improve sensor designs and resistance to failure. Their expertise as a ceramics company allows them to control the ceramic element from raw material to the finished product, ensuring a well-built component that fits right.
