NGK Nissan Maxima 2003-2002 Direct Fit Oxygen Sensor

This NGK oxygen sensor is what you get when you need to replace the one on your 2002-2004 Infiniti I35 or 2002-2003 Nissan Maxima. Oxygen sensors are a key part of your car's diagnostic system. They help keep the engine running smoothly, get the best possible gas mileage, and cut down on exhaust pollution. By sending information back to the car's computer, they help manage the air and fuel mix and alert you if there's an issue with how the engine is getting fuel or if the catalytic converter isn't working right.

NGK, a major supplier of original equipment oxygen sensors, uses advanced technology in their ceramic elements. This particular sensor features a special overcoat that acts as a trap for contaminants and has a three-stage plasma jet. This design helps protect the sensor element from poisoning, which can happen over time from exhaust gases. Because NTK is involved from the very beginning of sensor development with car manufacturers, they build sensors designed to perform well and resist common failures.
