I need to replace my 02 sensor and I saw Bosch universal 02 sensors for the M42 for sale on ebay, has anyone ever bought one? any good?

If it's from bosch it'll work as well as the origional, provided you splice it in to your harness correctly.

never bought it, turned out my o2 was fine. But like the others said, it's from bosch so you know it's good...just make sure it's a 4 wire.
