Item Details
TRQ oxygen sensors are manufactured to precise specifications using premium raw materials to optimize your vehicle’s emission system. 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. All products are fit and road-tested in our Massachusetts R&D facility to ensure we deliver on our promise of Trusted Reliable Quality.

I put in the new ones and they lasted 30 day. Put the old ones back in and worked better. Was trying to do preventative maintenance

Purchased a 2012 Subaru Impreza Base 2.0I and the engine light was on due to catalytic converter code. Previous owner had the catalytic converter replaced 2 years ago but they never replaced the sensors so I decided to try the sensors first. Worked like a charm! Now my cruise control works again. Definitely recommend.

The O2 Sensors were a perfect match and once I cleared the Check engine light, I have not received any new Check engine errors for sensors. I also like that I could see a video on location and how to remove and install new sensors.

The back sensor was fine. The front one, Bank1 gave me o2 heater fault. put the old one back and everything was fine, tried clearing the code several times, until i reinstalled the old sensor. Maybe I got a bad one? the connecter is different than stock. does not fit 2016 forester xt.
