Was Skeptical, but overall an excellent value.
Purchased these awhile back for my 2004 Jeep Liberty. Only used the upstream sensors at first and it corrected the rough running issue, but the check engine light was still on, so went ahead and installed the downstream sensors also and so far, after several hundred miles everything is running smooth and I've noticed better gas milage and check engine light has remained off. I highly recommend for the price. The only strange issue is that the upstream and downstream sensors are almost identical with the same part number, but apparently work just fine.

Spend the money the first time and go OEM
Installed sensors to have fuel trims all over the place and vehicle missing at idle. Changed spark plugs and injectors thinking issue couldn’t be with new set of sensors as they were registering data . Ended up going back with OEM sensors although expensive truck has been operating perfect with good learned trim values for the last 200 miles. Sometimes dollar value costs headache in the long run. After reading other reviews found similar issues with other customers. Would highly suggest NOT purchasing and going OEM.

Perfect Replacement
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

Work as designed
I replaced the O2s with the exhaust when the catalytic converter went bad, so they original ones I had may or may not have been any good. Since the check engine lights stayed off, it appears these worked as designed. NOTE WHEN INSTALLING: the sensors are not labeled as upper or lower. You have to look at the notch inside the wiring harness and compare it to the original. If the vehicle harness will not easily clip onto the new sensor harness, then the notch alignment is causing the issues.UPDATE: 12/30/24. Within a few days of installing the new sensors, one failed. Within one year, both bank 1 and bank 2 were throwing multiple codes. I replaced them with over the counter parts from O’Reilly and the codes cleared, allowing for me to pass inspection.

Plug and play
Solved my issues, blew both my catalytic converts out and smoked my o2 sensors. I have used TRQ on various parts I replaced and would definitely suggest them overall for more than just 02 sensors. Been now a month and car runs great!
