I've got to just say that my 1998 (all stock) Boxster w/ manual trans and 87,000 summer driving only miles, has the orginal IMS and I have no plans to touch it. I've talked to 3 Porsche dealer veteran mechanics and a large Chicago "indi" shop specializing in Porsche's, Audi's and Mercedes......in total they claim to have only seen 3 Porsche's that have suffered a IMS failure in the last 15-20 yrs.

To be fair, a couple did say that if one was to do the clutch, then it's probably "not a terrible idea" to change out the IMS bearing but none thought it was something that needed to be done proactively. They believed it all depends on the overall condition and value of the car as to if it makes sense to JUST do the IMS.

I suppose everyone has their own take on the subject....at one time there was a survey/poll on this Forum but I can't seem to find it.
