Product Features
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.

Works great thanks
Pricing was great. Got shipped to me ahead of time that was originally quoted
The part came in fast and they fit like a glove. The best online store to shop for parts. I will only order parts for here now on.
I found everyone to be straight and professional. I like the quality in the parts.
Fit my Hummer H2 and fast shipping
The sensors were exactly what I wanted. Fit perfectly. Couldn't have been more satisfied.
These sensors clearly made a difference because I replaced them one at a time and checked the OBDII and the code for each disappeared as I changed them. It smoothed out the running of the engine. The only thing that could have gone easier is if the right bank sensor could have come out as easily as the left bank sensor. But, 1A Auto isn't responsible for seized sensors. That's where your DIY experience comes in!!
Exact fit and truck runs better!
Everything was perfect, just as described!! My order was shipped right away and arrived nicely packaged in a manner that protected my sensors!
Works great - Thank U
These sensors will fit on either the downstream or upstream position depending on the vehicle you are purchasing for. Please be sure to match all of the specifications in the listing with your vehicle prior to ordering.
This would depend on what vehicle and engine size you have.
