      All;
      
      So, the REALOEM part # references the POST O2 sensor in Amazon.com as this one.
      
      Is that the POST cat O2 sensor we want?
      
      Thanks

      Not sure on that. When you use the 'vehicle part finder' at Bosch's (USA) site you get:
      
      13477 Oxygen Sensor - OE Type - Exact Fit - Upstream Sensor Two required; 4 Wire; Heated; Check / Replace Interval: 100,000 Miles
      V8-4941cc 5L FI EngDesg S62 GAS
      
      13475 Oxygen Sensor - OE Type - Exact Fit - Downstream Sensor Two required; 4 Wire; Heated; Check / Replace Interval: 100,000 Miles
      V8-4941cc 5L FI EngDesg S62 GAS
      
      Just search Amazon for 'Bosch 13477' for pre's and 'Bosch 13475' for posts. I shoulda put these numbers in my original post. If a mod here wants to add this to my first post be my guest.
      
      edit: Oh wait I see it says 13475 in the description and also 2000-03 M5. Yeah...these are the posts. Good price, but if you look closely you'll see these are NOT Bosch sensors. If you search the way I described you'll always only find Bosch sensors.
