NGK 2007 Nissan Altima OE Type 4-Wire A/F Sensor

This NGK 4-wire Air Fuel Ratio (A/F) sensor is built to OE specifications, meaning it's made to work just like the original part on your 2008-2009 Nissan Rogue. A properly functioning A/F sensor is key to your engine's performance and fuel efficiency. It measures the amount of oxygen in your exhaust gases, sending that data back to the engine control module (ECM) so it can adjust the fuel-air mixture for optimal combustion. If your check engine light is on and the code points to an oxygen sensor issue, replacing it with a direct-fit part like this NGK sensor is a smart move.

NGK is a well-known name in ignition and sensor technology, and this sensor is designed to meet the exact requirements for your specific vehicle. The 4-wire design is standard for many modern A/F sensors, allowing for both signal and heater circuit functions. Installing a new A/F sensor can help restore lost fuel economy, smooth out rough idling, and ensure your engine is running cleanly and efficiently. It's a critical component for keeping your engine running right and passing emissions tests.
