NGK Nissan Altima 2011-2007 Direct Fit 4-Wire A/F Sensor

This NGK Air-Fuel Ratio (A/F) sensor is what you need to keep your engine running smoothly and efficiently. It's a direct-fit replacement designed for a range of Nissan and Infiniti vehicles, including models like the Nissan Altima, Infiniti G35, and Nissan Pathfinder. This sensor is a crucial part of your vehicle's onboard diagnostic system, working to ensure your engine gets the right amount of fuel for the air it's taking in. Getting this mixture just right is key to maximizing fuel economy, reducing harmful emissions, and keeping your engine performing at its best.

NTK, a major OEM supplier, builds these sensors with an advanced ceramic element that's protected by a special coating. This design helps resist contaminants and deposits that can poison the sensor over time, which means it should last longer and keep working accurately. Because it's a wideband sensor, it gives the engine's computer (ECU) a very precise signal, allowing for continuous adjustments to the air-fuel mixture. This level of control helps achieve the best possible combustion and the lowest emissions.
