Each sensor is isostatically-pressed for improved strength and durability, and plasma-sprayed to improve sensitivity and prolong the service life of the sensors. Oxygen sensors wear out over time and should be replaced every 60,000 miles to prevent poor engine performance. TRQ recommends replacing the oxygen sensors in sets to optimize fuel economy and reduce overall emissions.

I replaced the oxygen sensor in my 1998 Subaru Forester with this TRQ O2 sensor, and the check engine light finally went off! It installed without any issues and seems to be working perfectly. Definitely a solid buy for anyone with an older Subaru.

Didn’t last as long as expected
I was happy with this sensor when I first installed it in my 1999 Subaru Forester, but it failed after just a few months. It was easy to install, but I expected better longevity. Not sure I would buy again.

Installation instructions could be clearer
I got the TRQ O2 sensor for my 1998 Impreza, and while it works fine now, I found the instructions a bit confusing. It took me a bit longer to figure it out than I thought it would. Still, it did the job once I got it installed!

Good but took a while to arrive
The TRQ O2 sensor works great in my 1999 Impreza, but the shipping took longer than I expected. Once it arrived, I had no trouble installing it. Just wish the delivery was quicker, since I needed it right away!

Great quality for the price
Very satisfied with my purchase of the TRQ O2 sensor for my 1996 Legacy. It works just as it should, and the price can't be beaten. If you're looking for a replacement part, this one's worth it!
