Lambda Oxygen Sensor for Subaru 22641-AA360/22641-AA370
Upgrade your Subaru’s emissions system with the Lambda Oxygen Sensor designed for Subaru 22641-AA360 and 22641-AA370. This upstream, heated O2 sensor uses a precise piezoelectric sensing element to deliver accurate oxygen readings right from engine start, helping your car maintain optimal air-fuel balance, lower emissions, and improve fuel efficiency. Built to match OEM specifications for 2.5L H4 engines, it’s a reliable replacement that keeps your Subaru running smoothly across models like Forester (2002-2010), Impreza (2005-2011), Legacy (2006-2009), Outback (2006-2009), and even Saab 9-2X (2006).
Produced by IWOKPHD, this sensor is engineered for stable installation and dependable performance. It carries OEM numbers including 234-9123 and supports multiple part references (22641-AA360, 22641-AA370, 22641-AA36A, 22641-AA180) to ensure you’re choosing a correct upstream oxygen sensor for your vehicle. The integrated heating element speeds up warm-up for faster accurate readings, which translates to better throttle response and more consistent engine operation in both city and highway driving.
All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
