I'd skip it -- becuase what it does is fool the system to think it's running lean so it pumps more fuel in; making it really run rich. (or is it the other way around?, which would be worse....)

I bought the Bosch replacement for a Ford Mustang and spliced the old pigtail on. It runs the same as the BMW version for $42.00 and 30 minutes of my time. Autozone wanted over $120 for the identical sensor with a different connector. Why would you want something from a website that can't spell correctly and uses bad grammar? Kinda says something, eh? What model BMW do you have? Sometimes cross matching can save money and time.
