NGK Volkswagen Passat 1993-1991 Direct Fit Oxygen Sensor

This NGK oxygen sensor uses an advanced ceramic element that's protected by a 3-stage plasma jet and deposit trap overcoat. This design helps prevent contamination, which is crucial because oxygen sensors are a key part of your vehicle's onboard diagnostic system. They constantly send feedback to the ECU about the air-fuel ratio, helping your engine run at its best, get good gas mileage, and keep emissions down. If the sensor isn't working right, it can also alert you to potential issues with your fuel system or catalytic converter.

As the world's largest supplier of OEM oxygen sensors, NTK (NGK's sensor division) has a lot of experience here. They control the entire process, from the raw materials to the finished ceramic element, ensuring a well-built part. This direct-fit sensor is designed to work seamlessly with your 1991-1993 Volkswagen Passat, making installation straightforward.
