Default PSA for those who need to replace the rear O2 sensor

Bosch 16121 is a direct fit: the connector fits perfectly and the wire is just a few inches longer than what's needed.

at ~$60 through amazon, there's no reason to spend the $200+ for a new OEM sensor. hope this info helps!

Might be time to stock up before they get really expensive....;-/<ul><li><a href="http://www.amazon.com/Bosch-15733-Oxygen-Sensor/dp/B000BZG8ZU/ref=pd_sbs_auto_2">http://www.amazon.com/Bosch-15733-Oxygen-Sensor/dp/B000BZG8ZU/ref=pd_sbs_auto_2</a</li></ul>

given the simplicity of the 16121, it may be worth the extra $10-15

Default can be easy or hard

depends on how seized your old sensor is. I tried to replace mine last night with the car on ramps but just couldn't get enough leverage to break the old sensor loose. a quick trip to a local shop took care of the replacement though.
