Item Details
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.

Worked perfectly, no more check engine for P420 emissions code. 👠Would recommend!

These units did not work as advertised. When installed, they caused fault codes which were difficult to diagnose. They caused one bank of the fuel system to go into full fuel mode which caused a bad misfire once the engine warmed up. Had to go back with the Bosch OEM sensors at a cost of over $400.00 and pay $300.00 in fees to diagnose the problem.

Got these to replace the 110,000 miles ones on my Nissan 350z. I was concerned because I've always heard how particular Nissan's are with their parts and how most HAVE to come from Nissan specifically.Well, these fit perfect and work perfect! My car is driving brand new again!Highly recommend

Good price.No labels to identify up/down stream sensors but connections prevent incorrect installation. Two different designs on the downstream sensors. Not enough anti-seize on two sensors. Not unexpected for DIY project.Only 1 sensor on first order and Amazon corrected problem.

I am extremely upset with my orders . I have ordered this products three times the first time I only received one sensor that did not fit . Then I orders again and received 4 sensors none of them fit on my vehicle . Then I decided to get more sensors hoping that they would fit my vehicle . None of them is working and now I’m stuck with 8 sensors . All of this was night nightmare and I’m so disappointed I hope they will do something about this

I bought 4 new sensers after 3 months 2 failed. Asked for warranty, told by Amazon it was after there 30 days not willing to do anything. Totally surprised...disappointed by this transaction.
