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 installed this TRQ downstream O2 sensor in my 2002 Subaru Forester without any issues. It fit perfectly and now my check engine light is off! Can't beat the price for a quality part like this.

Not as good as expected
I had high hopes for this because of the decent reviews, but the sensor stopped working after just a few months. I guess I’ll have to look for a more reliable option next time. Disappointed with this one.

Solved my emissions issue
After replacing the old O2 sensor with this TRQ one, my Subaru Forester passed emissions testing with flying colors! Installation was easy, and I’m happy with the performance so far.

Decent sensor but took too long to arrive
The O2 sensor works fine, but it took a week longer than I expected to get here. Once it finally arrived, installation was straightforward. Just wish shipping was a bit quicker!

Instructions could use improvement
While the sensor seems to work well on my 2003 Subaru, the installation instructions weren't very clear. It took me a little longer to figure it out than I wanted, but it's working now!
