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.

The product fit and seems to work perfectly.
Not all of the parts worked so I ended up getting a partial refund. Frustrating of course since I had to go buy new one's at the local auto parts store.
I have a 2007 Ford E350 super duty van And I bought the O2 sensors for the upstream and downstream And they work great. Great price .
Great parts and great service

I believe it contains both as I just got the part as well. I havent checked them out yet but once I do I will let you know.
Yes, this kit will include two upstream and two downstream sensor. These parts are listed to fit 1997 Ford Mustang.
Sorry for the late response. Should say lean bank 1 or bank 2 on the code reader. Not sure which is which. Gotta Google that
Upstream and downstream have different noticeable connectors making it easy to figure out. Sensor 1 or upstream is before the cat and closer to the engine, whereas sensor 2 or downstream is after the cat and farther from the engine.
This will fit a 2005 Ford Mustang V6 4.0L or V8 5.4L
