NGK Subaru Crosstrek 2017-2016 Direct Fit Oxygen Sensor

This is the NGK oxygen sensor, part number 24651, designed to fit a wide range of Subaru vehicles including the Crosstrek, Forester, and Impreza. Oxygen sensors are a key part of your vehicle's onboard diagnostic system. They help keep your engine running at its best by constantly monitoring and adjusting the air-fuel mixture, which also helps maximize your fuel efficiency and reduce harmful emissions. When an oxygen sensor isn't working right, your car's computer can get incorrect readings, potentially affecting fuel delivery or the catalytic converter's performance.

NGK, a major supplier of original equipment oxygen sensors, builds these with an advanced ceramic sensor element. This element features a special plasma jet and deposit trap overcoat that resists contamination, helping to prevent poisoning and ensuring the sensor works correctly for longer. Because NTK is involved from the raw material stage through to the finished product, they have a lot of control over the quality of the ceramic element, which is crucial for accurate readings. This sensor works by sending constant feedback to your car's ECU (Engine Control Unit) to help maintain that optimal air-fuel ratio.

If your check engine light is on and you suspect an issue with your fuel system or catalytic converter, replacing the oxygen sensor is often a good first step. This direct-fit sensor is designed to install easily in place of your original part.
