Amrxuts 2Pcs 234-9123 234-4445 Upstream Downstream Oxygen Sensor for Subaru 2006-2011 Impreza 2006-2009 Legacy 2006-2010 Forester 2006-2009 Outback 2006 for Saab 9-2X 2.5L-H4 22641-AA36A 22690-AA810

Bough these for my 2010 Subaru Forester. I also bought a new Catalytic converter as the same time. Decided to put new Oxygen Sensors in at the same time. These worked perfect. No check engine lights and passes inspection. I have driven over a thousand miles with these parts so far.

Muy buena calidad me funcionó

Used these on my 2008 Subaru Impreza to replace the OEM stock sensors that were never replaced on it. After I got them off, the old ones were ash gray, completely shot. These were a great replacement because oem ones would have totalled $300, but these work perfectly fine. One problem though, especially for Subarus, is that the ECUs in Subarus are very very picky, so while my car is now running better than it's been in 15 years, the check engine light is still on with the same o2 sensor error code, which is something to keep in mind for inspections. Overall though, car runs incredible.

Failed after 4 months. Do not go cheap on O2 sensors for a Subaru. Buy quality Denso sensors.

Easy to install. So far engine is running better because of it

I tried to register my vehicle at MVD but the emission test failed because the check engine light is on. I dropped my vehicle in the shop to get estimate the work to resolve the check engine light. Finally they came up with a list of 3 major things got to be fixed. One of those are the work to resolve check engine light. Total cost was about 3 grants. I said my vehicle not likely be valued more than 2 grants but fixing it costs 3 grants. I'm not going to do it. I did the search on YouTube and started to gain idea what I can do to solve the problem myself with the lowest cost. I just need couple of O2 sensors to solve this problem. I checked couple auto part shops and realized they're selling better name sensors but double the price. My vehicle is old so I don't know how long it's going to last. I decided to get these lower price to test them out. After replaced with these sensors for my 2007 Subaru Outback, the check engine light is gone. I brought the vehicle back to do emission test and it passed. That's all I need. Now I just wait and see how long these sensors still functioning as expected.

check engine light went away and passed new york state inspection. really surprised. great products

Only one sensor was correct. Up stream connector had an incorrect harness clip
