Upgrade your Subaru’s engine management with the Air Fuel Ratio Lambda/O2 Sensor designed for Forester, Impreza, and related 2.5L models. This upstream oxygen sensor uses a heating-type, magnetic induction design to deliver fast, accurate Lambda readings. By maintaining the correct air-fuel balance, it helps your engine run more efficiently, reduces emissions, and provides a smoother, more responsive driving experience on compatible 2002–2004 Legacy/Outback, 2003–2004 Forester, 2003–2004 Impreza, and 2003–2006 Baja NON TURBO 2.5L vehicles.

The sensor supports multiple OEM part numbers to maximize compatibility, including 22641-AA230, 22641AA230, 22641 AA230; 22641-AA140, 22641AA140, 22641 AA140; 22641-AA280, 22641AA280, 22641 AA280; and 234-9015, 2349015, 234 9015. Originating from Mainland China, this unit is built to meet the demands of Subaru’s upstream Lambda sensing with a heating element for rapid response in varying climates.
