Product Details
The ceramic element in this NGK oxygen sensor uses a 3-stage plasma jet and deposit trap overcoat. This design helps protect the sensor from contaminants, which is crucial for its job of monitoring your 2001-2003 Infiniti QX4's exhaust gases.
As a key part of your vehicle's on-board diagnostic system, the oxygen sensor constantly sends feedback to the engine control unit (ECU). This information helps maintain the right air-fuel ratio for optimal engine performance, better fuel efficiency, and lower emissions. If the sensor isn't working correctly, it can also alert the OBDII system to potential issues with fuel delivery or the catalytic converter.
NGK is a major supplier of original equipment oxygen sensors, meaning they work closely with manufacturers from the start of development. This ensures the sensor is built to meet the specific needs of your QX4.
