IMS bearing risk depends on year and engine

Porsche Boxster 987 · mechanical

The intermediate-shaft (IMS) bearing concern applies to 987.1 (M96/M97) cars. 2005 cars carry the most failure-prone bearing; most 2006-2008 cars received the larger third-generation single-row bearing considered more robust; the 2009+ 987.2 DFI engine eliminates the IMS entirely.
