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.

Easy ordering and good parts
I gave it a 3 star because once I installed then my OB2 sensor is showing heater control circuit low bank 2 sensor 1. Too much trouble to buy other ones and change them.
I would not recommend buying this one, I bought one and it only lasted a couple of months, I then bought an o.e.m. and it has lasted over 3 months and still going strong. The warranty says a yr but it's like all other warranties, it's not honored.
Worked great on my 06 sonata and shipping was fast. I would recommend
I usually end up finding all the parts I need here. Every part I have ordered fits and works, including this order. Definitely will order again when I need parts.
OSA61781
