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, 2002-2003 Nissan Maxima, or other compatible Nissan and Infiniti models. As a key part of your vehicle's on-board diagnostic system, oxygen sensors constantly send information to the engine control unit (ECU) about the air-fuel mixture. This feedback helps the ECU keep the engine running smoothly, maximize your gas mileage, and reduce harmful emissions. When an oxygen sensor isn't working right, your car's computer can detect issues with fuel delivery or the catalytic converter.

NGK, known for its ceramic expertise, builds these sensors with an advanced ceramic element. This element features a three-stage protective coating that acts as a plasma jet and deposit trap. This design helps shield the sensor from contaminants that could poison it, leading to a longer service life and more reliable readings. Because NTK is a major OEM supplier, they work closely with manufacturers from the initial design stages right through to production, ensuring their sensors perform as expected.
