1A Auto Lifetime Warranty

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.

Great Delivery Service

I ordered the parts and received them in 3 days. All parts were exactly what I needed.

Good Replacements

Samuel

So far so good. I replaced oem units for these about 100miles ago and the "check engine" light has not come back. The pigtails are a few inches longer than oem which was somewhat helpful. They certainly appear and feel like quality units. I will change my rating if anything changes, but if you're reading this now they're still working great.

My car didnt react to the sensors...

Jean

My scanner revealed that only bank 2 was reading ... bank 1 was completely disfunctional.

O2 sensors

Excellent

These were a lot cheaper than factory, but not sure it was the right choice.

Johnny

Box was not marked as to where to place it. The wires were different length to the factory ones. I bought all 4 sensors for my Xterra, so hard to figure which one went where. And my scanner tells me the other bank has a bad one.

Hello Friend! I own a 2005 Nissan Pathfinder and there's several things u nd 2 knw. 1. There's a recall for a known issue in the fuse box that causes a short and the engine to stall when driving. 2. If you haven't done so already, switch your Nissan radiator with an aftermarket one a.s.a.p. or you'll spend $5,000 replacing the transmission!! The factory radiators leak coolant into the transmission and KILL it and the Valve Body around 90-100K Miles. Trust me, I spent 7K doing it twice because I didn't believe it!
