Looks like OEM O2 sensors are about $100 for the pair (before and after). Plus labor. I try really hard to avoid working myself on this car . . .

When I get around 100K miles on a car I replace the O2 sensor(s), at least the pre-cat ones. I figure they get old and lazy and new ones keep everything running well.
I just went through smog testing today on my 192,000 mile 325i (original cats), passed with no problem.
