BMW F25 X3 28i N20 2.0L Engine O2 Oxygen Lambda Heat Sensor Set OEM

BMW F25 X3 28i N20 2.0L Engine O2 Oxygen Lambda Heat Sensor Set — taken from a 2011–2018 BMW F25 X3 that came through our Texas yard. The donor car had 88k miles on the clock. What you see in the photos is the part that ships — no stock images.

The oxygen sensor reports the mixture to the engine ECU. Pre- and post-catalyst sensors and cable lengths differ, so check the position it came from.
