Amrxuts 234-9108 Air Fuel Ratio Upstream O2 Oxygen Sensor 1 for Subaru 2011-2013 Forester 2.5L-H4, Subaru 2011-2013 Impreza WRX 2.5L-H4, 22641-AA590

First one went bad after 3 days. Waiting on 2nd one to arrive hopefully no issues. These have sensor and sometimes they get damaged in shipping. Last one I bought 3 years ago. 50 compared to 200 is a deal to me. 2nd one went out at 52 miles after replacement. Sending back and ordering a denso sensor.

Just put this o2 sensor on about a month ago and it's already not working

Was iffy on buying this sensor because I never heard of this brand and always buy denso products. But to my suprise it works perfect. Great quality and works perfect.

Works surprisingly well for the price

I had bought this product to replace my oem sensor, bolted right up but after about 10 minutes of driving I think it already died. CEL is back and I’m idling funky again…

Didn’t even work check engine stayed on don’t buy

This part does not fit my 2011 Subaru Forester.

My 2014 WRX had a check engine light come on (P0031) (Up Stream O2 Sensor Failure), I cleared the codes a few times but they would pop up as soon as I turned over the ignition. After some research I knew I would need to replace the O2 Sensor. I decided to give this product a try. Showed up after a few days, installed in about an hour. Perfect fit, looked just like the OEM one that I took out. I cleared the CEL, fired her up and no more codes. I've put about 500 miles on it so far with no issues. Make sure you pick up an O2-Sensor socket adapter, this is a must for installing. Tip for removal of the old O2 Sensor, cut the wires and use a deep socket + Impact to back it out of the exhaust, don't try to use the adapter to remove!! . Happy Wrenching!
