I'm not sure there is really that much of a benefit to a screw-on... filtration-wise, that is. With the original filter I can easily inspect the filter for metal, that's a real benefit to the original filter system.

Plus, It's hard for me to imagine that the Porsche engineers haven't considered these issues (IMS bearing issues not withstanding!).

Consider that we are running 9 quarts of oil, that's a lot... and not that big an engine. Also, most of us change about every 3,000 to 5,000 miles or once a year, whichever comes first. That's not asking too much of 9 quarts of oil, especially the high-end synthetics we all use. This filter thing seems like an unneeded expense to me.
