NGK Nissan 200SX 1987-1986 Direct Fit Oxygen Sensor

If you're noticing a check engine light or a drop in your gas mileage on your 1993-1998 INFINITI Q45, a failing oxygen sensor could be the culprit. This sensor is a key part of your car's onboard diagnostic system, constantly feeding information to the engine control unit (ECU) to keep the air-fuel ratio just right. Getting this part replaced is crucial for maintaining optimal engine performance, maximizing fuel efficiency, and reducing harmful emissions.

NGK, a well-known name in ignition and sensor technology, builds these oxygen sensors with an advanced ceramic element. This element features a 3-stage contaminant-resistant plasma jet and a deposit trap overcoat. This design helps protect the sensor from poisoning and ensures it can accurately report back to the ECU, even in challenging conditions. Because NTK is the world's largest supplier of OEM oxygen sensors, you can trust their expertise in creating a part that works seamlessly with your vehicle's systems.

This sensor is designed as a direct fit for your vehicle, meaning it should install without needing any modifications. Replacing a faulty oxygen sensor is a common maintenance task that can make a noticeable difference in how your car runs and how much fuel it uses.
