Upgrade your Subaru with a reliable Oxygen Sensor Upstream/Downstream Lambda set, designed to deliver precise air-fuel monitoring for Forester, Impreza WRX, and related models. This dual-sensor package includes OEM-style replacements 22641-AA420 and 22690-AA900, enabling accurate readings from both the upstream and downstream exhaust streams. By providing exact lambda data to the ECU, it helps optimize combustion, improve throttle response, and reduce harmful emissions.

Built for durability and consistent performance, these sensors feature a heating-type design with a piezoelectric sensing element for fast warm-up and stable readings across operating temperatures. This means quicker recovery after cold starts and more reliable fuel-trim control, contributing to smoother drivability and better exhaust protection. The kit is compatible with a broad range of Subaru vehicles, including Forester 2011–2013 and Impreza/WRX variants across 2010–2014, among others listed in the application details.

Each item is factory-tested to closely match original specifications, ensuring a precise fit and dependable operation. For best results, verify fitment against the models and OEM numbers shown before installation. If you’re unsure about compatibility, contact us before purchasing and we’ll help confirm the right part for your car.

Benefits & Tips

  • Restore accurate oxygen sensing to improve ECU fuel-lean/rich adjustments, which can enhance throttle response and overall drivability.
  • Faster sensor warm-up reduces cold-start delay and supports stable catalyst efficiency and emissions control.
  • Tip: After installation, clear stored codes with an OBD-II scanner and monitor engine performance to ensure optimal tuning.
