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.

So far so good...usually I tend to go with the original part but money was tight and took a risk on this set and the vehicle is doing great now
Perfect fit, check engine light is no longer on. I have nothing but positive experience with 1A auto and have ordered several parts from them.

Order was quick and easy. The videos was very helpful, I like the fact you can view on how to install before you buy.
Good product, good fit, good price. 1A Auto continues to meet my needs
Ordering was accurate and easy. I received the pet sooner than expected. Unfortunately, the sensors in the car were good and did not need replacing. The error code was due to a loose connection which created a faulty reading. Returning the items was quite easy as well. I am still waiting on the refund but returning the items was simple.
Good product fast shipping:)
Works great in my 2016 Nissan Altima
