  Air/Fuel Sensor - Subaru (22641AA80A) is a Genuine OEM component engineered to deliver accurate real-time feedback on the air-fuel mixture entering your engine. This wideband sensor is essential for maintaining efficient combustion, optimizing engine performance, and ensuring emissions remain within regulatory limits. Designed to meet Subaru’s strict quality standards, it offers long-term reliability for both professional mechanics and DIY enthusiasts working on compatible Subaru models.

  Manufactured with a high-sensitivity zirconia element, this sensor is housed in a corrosion-resistant stainless steel body, built to withstand extreme exhaust temperatures and engine bay conditions. The sensor continuously monitors the oxygen content in the exhaust gases, allowing the Engine Control Module (ECM) to fine-tune fuel injection and ignition timing with precision. The result is smoother throttle response, improved fuel economy, and reduced emissions.

  Installation is straightforward, with the sensor threading directly into the exhaust manifold or header and connecting via a sealed OEM-grade harness. No additional adapters or calibration are needed when replacing with this exact-fit component. The ECU recognizes and communicates with the sensor immediately, restoring accurate engine control functions without delay.

  Using the Genuine OEM Air/Fuel Sensor avoids the common pitfalls associated with aftermarket alternatives, such as poor signal accuracy, incorrect fitment, or early failure due to inferior materials. With the 22641AA80A, you're maintaining factory-specified performance and reducing the risk of check engine lights, drivability issues, or diagnostic trouble codes.

  Key benefits of the Air/Fuel Sensor - Subaru (22641AA80A):

  ✔ High-accuracy oxygen sensing for precise air-fuel mixture control

   ✔ Durable stainless steel housing resists heat, vibration, and corrosion

   ✔ Direct-fit design ensures fast, hassle-free installation

   ✔ Maintains factory emission standards and engine efficiency
