Yes I'm getting a PPI, but was just curious if anyone here at insight on an OEM IMS fix. The price of the part seems ....low. I will call the dealership to confirm, but back in 2011 would they have simply replaced it with a then better quality dual-row IMS? Or the same part prone to failure from the original?

Leaking oil seals on the IMS cover flange were a common occurrence and the corrective measure was to replace the flange seal only. As Porsche has never admitted that the IMS bearing itself can be changed without pulling the engine apart, most dealers did not get involved in retrofits, replacing the entire engine if there was an issue.
As yours is 2004, it is a single row bearing, which can only be replaced with another single row bearing; the dual row will not fit.
