Product Details

If you're working on your 2015-2021 Subaru WRX or 2014-2018 Forester, this NGK direct fit B1S2 oxygen sensor is what you need. Oxygen sensors are a key part of your car's diagnostic system, helping to keep the engine running smoothly, get the best possible gas mileage, and keep emissions in check. This sensor sends information back to the car's computer to manage the air-fuel mixture and alert you if there's an issue with fuel delivery or the catalytic converter.

NGK, a major supplier of original equipment sensors, builds these with an advanced ceramic element. It features a three-stage protective coating that acts like a shield against contaminants and deposits, which can poison the sensor over time. This helps ensure the sensor works reliably and lasts longer. Because NGK works directly with car manufacturers from the start of development, you can trust that this sensor is designed to perform well and resist common failure points.
