OEM the best?
When I replaced the O2 sensor in my old Dodge Spirit I cheaped out and went with a Bosch. It crapped out after 40,000 km...the OEM one had lasted around 260,000 km.
I've heard this is relatively common. OEM components just seem to last longer than aftermarket in my experience (I had the same issue with some Monroe struts compared to the OEM struts from Dodge - OEMs lasted 3x the distance).
