Difference between these 2 Bosch sensors?
Just trying to figure out what the difference between these two sensors are. If my O2 sensor is out, might as well replace it with an upgrade. Both are for upstream and I know it's wideband but I'm a little confused here...

Premium Oxygen Sensors

Wideband Oxygen Sensors

Simple the Premium Sensor isn't a wide band.

The ECU is expecting a Wideband input.
Furthermore I believe the front O2 is a 4 wire heated sensor.

I used the vehicle finder as well and assumed that the one that you mentioned above is the correct also, I was just searching around and researching possible upgrades/possibilities. And I came across those two and was a little stumped as I know the front is wideband..

Both front and rear are 4 wire heated O2. Exact same connectors. But front is wideband, rear is narrow band. The first 3 words in the description of each indicate which is narrow and which is wide.
