I do need to point out that their are two "upgrades" to the IMS: the "IMS Retrofit" and "IMS Solution".
IMS Retrofit | The LN Engineering IMS Retrofit Kit for MY97-05 Porsche Boxster and 911 Models
The IMS Retrofit is an upgrade but not a fix, IMS can still occur but is much less likely. Current price for the part is $650. Porsche essentially installed this in 2006+ 987/997.
IMS Solution does away with the bearings that would fail. It's currently $1,500
Then there is the IMS Guardian which is basically a magnet on a sensor that warns you if there are metal shavings in the oil. That's currently $260-$410.
IMHO every 1997-2008 porsche owner should have at least a Guardian. I will be having one installed come next oil change, since the sensor replaced the oil plug it's best to install when oil is drained. Even with a 2006 I worry, and IMS failure is not the only reason metal may be in the oil.
