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.

The parts worked great.
Died within six months. I can't speak for other brands but I have extensive history with my Nissan Titan and all but one (starter), off brand parts has failed. I only use Nissan OEM parts now. Discounted parts have cost me a fortune replacing them with Nissan version after they fail.
Great Product
Made well product. Very close to OEM. They only hard part about installing is actually taking the old ones off.
You can purchase a high-quality part and save money you cant ask for it better I ride with confidence and a piece of mind.
very please with my purchase of O2 sensors. My truck is performing quite well since they were installed! Items arrived very quickly and I could not be any happier! Thanks 1A!!
Very satisfied with product, customer services was great will always use you guys for future auto parts I will need
Love the easy and fast ordering and the fast delivery. I was very happy with the product. The only issue I had which is common was one of the O2 sensors was faulty but I called and got a replacement as fast as they could send me one. I will be ordering more parts from here!
So far great product, fit perfectly and got rid of my check engine light. Way cheaper in price than other O2 sensors as well so it saved me alot of money. The wiring harness is a little bit longer than stock which gives a you a little more play for aftermarket pipes. Only time will tell how long they will last, but even if I had to buy a second set I would still be spending less than other O2 sensors.
Worked perfectly! Cant recommend it enough!

This kit is listed to fit the: 2017 Nissan Titan V8 5.6L
Yes these are compatible with CA emissions.
Thank you for your inquiry. This will be dependent on your specific vehicle, however, the upstream and downstream will have different connectors. We would suggest removing the original O2 sensors on your vehicle and matching the connectors up the the O2 sensors you receive from us. Please let us know if you have any further questions.
