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.

Quality part, fit is the same as OEM, function is slightly dampened from stock sensor creating a more stable fueling.
Normally I don't "cheap out" on electrical components, but went ahead and ordered this. Needless to say it immediately fixed my issue. Install was quick and easy. Definitely recommend.
Did not fix the problem. Took to a shop and they had to replace with an oem sensor. It does not pay to cheap out sometimes.
Perfect fit on my car good product!
