Description
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.

Just what I ordered
Product was exact fit for the car I was putting it on. Delivered fast, they let me know when it would be there and it was there. I changed this part for a friend and saved her from paying a garage 450.00 . Took care of her check engine light without costing a fortune

P0137
I replaced both the upstream and downstream sensor (this one) and this one gave me problems, rough idle especially when the engine was turned on and my corolla threw off aa CEL for p0137 code, like I mentioned I replaced both and thankfully the least expensive one (this one) gave me the issue so i just put back the original one on and the car is back to normal.
