What is the difference between the Bosch OEM and "universal" 02 sensor? Can either be used. Looking at Autozone its interesting the difference in cost between the Focus and Contour. Contour SVT needing 4 makes the $99 hurt, the ford part websites has $113 as the cheapest I've found so far.
For example here is the listing from Autozone when searching for "oxygen sensor" for a 99 SVT contour (and for my 2000 Focus below - big difference there):
