This sensor recommendation is unverified, proceed at your own risk.
Lately I've been hearing through the facebook grapevine of 550i O2 sensors being recommended for single turbo use.
Then someone else told me they are the same as ADV, but I'm not sold on that claim. Realoem indicates they are placed post-turbine in the stock configuration so BMW would have no reason to use something designed for pre-turbine like the ADV.
The BMW PN is 11787576673, and they are also listed as Bosch 17187.
Anyone have any info or better a technical PDF of the sensor itself? So I may compare the lambda response curves etc against the ADV.
