Subaru OEM Rear Oxygen Sensor WRX 2015-2021 / Forester XT 2014-2018 | 22690AB010

Subaru quality parts and IIR deals. Can't go wrong.

Exact replacement for the OEM part. Bought this to hopefully fix the p0420 code. It wasn’t the problem but I thought it might be worth a shot. Looks like it may end up being the cat which is much more expensive. Was hoping to get out cheap and easy but no such luck. Not the parts fault though.

Exact match to my OEM Subaru oxygen sensor opposed to the “exact match” I bought on Amazon. So far (approx 250 miles driven) no check engine light and the WRX is running much smoother and getting better mpg again.

Upon failure of my rear O2 sensor, contacted IIR, got stock and invoiced for an immediate purchase and turnaround. Amazing! Sensor had a protective cap and had anti-seize applied when received. I got exactly what I needed faster than expected to solve an unexpected failure caused by driving through unavoidable water in the roadway. Awesome.

Oem every time for the perfect fitment. Fast shipping makes it even better

Thanks good

Thank you for service

My old sensor would read sometimes and not read others was time for a change out

With the right tools and a little patience installing the right parts can be a breeze, and it was. Subaru OEM parts are always the way to go and this was no exception. The ROS fit perfectly as it should and functioned flawlessly. A huge thanks to IIR for always having the correct parts on hand and excellent customer service. The tool set I got used for a deep discount at Advance Auto Parts.

The part shipped fast, thanks! Dirext oem replacement and fit. No more cel, thanks!
