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.

Perfect fit, solve my check engine light issue. Highly recommend buying parts from 1A Auto
Changed both factories ones for these and instantly started getting p219a and p219b. Scan tool shows oxygen sensor levels not right. Changed out for factory ones no more engine light and sensor data looks good.
Excelente
Still got check engine light on
Definitely need the special O2 sensor socket to get the old one off
Great
Poor quality now I need to buy another one Because one is not working any more
I love this parts store! Great prices, always ships fast and if you have any questions just call them and they help you out.
Fit fine. Well made. All is good as it is working right out of the box.
Our parts are exact replacements for your vehicle's OEM parts. As long as your vehicle specifications match up with our listing, these parts will directly fit and function like the originals. These sensors are heated.
I did down steam but when I called for help they let me know for this model up and down stream are the same.
