Subaru OEM Rear O2 Sensor for your 2015-2021 Subaru WRX and 2014-2018 Forester XT.
Probably one of the coolest things about the 15-21 WRX is that it comes with a factory wideband sense out of the box. When they go bad, your car will run meh, you'll have a check engine light and it just isn't a good time. This is the fix!

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!
