I installed this O2 sensor in my 2004 Subaru Baja, and it worked for a couple of weeks before giving me issues again. I guess I expected better quality from TRQ. Maybe I just got a bad one, but I’m not impressed.

Great sensor, simple setup!
Installed the TRQ upstream O2 sensor on my 2003 Subaru Forester last weekend. It was super easy to install, and my gas mileage has already improved. So glad I chose this product!

Works, but the color is off in the picture
I ordered this for my 2003 Subaru Outback. It works fine, but the sensor looks different from what I expected based on the picture. Not a big deal though, it’s performing as needed, just a little confusing at first!

Easy installation and works great!
I bought this TRQ upstream O2 sensor for my 2004 Subaru Forester, and it fit perfectly. Installation was straightforward, and I've noticed a smoother ride since I replaced the old sensor. Definitely worth it if you're having engine performance issues!

Good sensor, but delivery was slow
The O2 sensor from TRQ is doing its job for my 2005 Subaru Legacy. It’s responsive, and my check engine light is gone now. Just a bit disappointed with how long it took to arrive, a few days longer than expected.
