Definition -- O2 Sensor
oxygen sensors are used to confirm that the proper air fuel ratio is actually reaching the engine.
- This package includes 4 sensors, 2 upstream sensors and 2 downstream sensors.
- But they keep the same, which means that they have no differences.
- Upstream location is between the catalytic converter and the engine;
- Downstream location is between the catalytic converter and the tailpipe.
If you have a bad O2 sensor causing your vehicle to fail an emission test or run poorly then this is the part for you.

I purchased 4 and 2 failed after a full install. Ended up getting the Bosch one and it worked fine.

They lasted for three months. They are not worth the money I am not buying anything from Amazon again to hard to return so you get no warranty… junk
