NGK Nissan Altima 2006-2004 Direct Fit 5-Wire Wideband A/F Sensor

This is an NGK 5-wire wideband Air-Fuel Ratio (A/F) sensor, part number 24320. It's designed to work with a wide range of vehicles, including popular models like the Nissan Altima, Infiniti G35, and Subaru Impreza. This sensor is a crucial part of your vehicle's onboard diagnostic system, helping to keep your engine running at its best. Unlike older sensors that just tell the computer if the mix is rich or lean, this wideband sensor gives a precise reading of the air-fuel mixture. This allows the engine control unit (ECU) to make very fine adjustments, which means better combustion, improved fuel economy, and lower emissions.

NGK, a major supplier of original equipment sensors, builds these wideband sensors with an advanced ceramic element. This element has a special three-stage coating that resists contamination and traps deposits, protecting it from poisoning. This construction helps ensure the sensor lasts longer and maintains accurate readings over time, even in tough conditions. Because it's a direct-fit part, it's made to install without needing modifications, making the replacement process smoother.
