Is your Subaru’s check engine light on?
It might be time for a new O2 sensor!

This Amrxuts upstream oxygen sensor is designed specifically for 2010–2012 Subaru Legacy and Outback models with the 2.5L H4 EJ253 engine.

It’s a direct replacement for part numbers 22641-AA54A, 22641-AA540, 234-9097, and many others (check the full list to be sure).
With 4 wires and a 19.88-inch harness, installation is straightforward — just plug and play.

A fresh O2 sensor can help improve fuel efficiency, reduce emissions, and restore engine performance.

Built to last with a fast-reacting core and durable construction, it even comes with a 1-year warranty for peace of mind.
Before you buy, confirm your vehicle details and OEM numbers.

Keep your Subaru running clean and smooth!
