O2 sensors OEM vs Bosch Universal

[tyu333]

Hi guys

What's the difference between the OEM Bosch O2 sensors from the $tealer$hip which cost R3800 each and the Bosch universal ones that cost about R800??

These are for a s50b32 M Coupe.

This is the part I find strange when I look them up on RealOem, does this mean the O2 sensors for this car are only specific to this car?

have you tried ebay for originals? my buddy picked up his M5 o2 sensors brand new at less then half the price.... its worth looking into if you dont want to use the universal sensor
