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 as it should
The car is running pretty good after changing the oxygen sensor!
The sensor was the OE match for my vehicle. The video for removal/installation was helpful in knowing what to do. Straight forward installation, but it helped greatly being on a friends hoist ane he had the right tool. Free shipping is nice, just know it takes a little longer to get to you. If you need it quicker you will have to pay. I would buy from 1A Auto again. Satisfied all the way through the process.
Perfect fit. Engine light turned off and inspection passed.
Good quality
Perfect fit, looks like the one I replaced. No check engine light so far. Working just fine. Will definitely recommend 1A auto. I bought other products before, never disappointed.
Put it in with my local mechanic and no issues. Thanks!
Was good and worked well,thanks
