You have 4 sensors, 2 pre-cat, 2 post-cat. Last I checked, pre-cat was about $40 and post-cat around $90. Post-cat is essentially the same sensor as the former, but with a longer wire. They're made by Bosch. The stealer marked the backs up by like 3 or 4 times. StealMW Mississauga wanted $320 for each back when I needed them a few years ago.
