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.

Well, what can I say it was easy to install but the engine light is still on. Although, every where I search and researched it said it takes about 20 cycles and driving it for a few miles.
I ordered this and the upstream sensor a few weeks ago. Removing the old ones were a PAIN, but installing was extremely easy. They come with anti-sieze preinstalled on the threads. The price and quality is unbeatable. I highly recommend on buying these.
It was easy to order and product arrived in a timely manner and it was the right part.. they work to make sure its going to work before you order.
OSA61778
Yes it is according to my mechanic.
We would be happy to check. What is the year, make and model of the vehicle as well as the engine size?
headers make no difference as long as there are holes for your oxygen sensors in your exhaust before and after the catalytic converter. If that was your question?
