Spin-on Oil Filter Adapter for MY97-08 Boxster/Cayman/911 - Parts & Upgrades - Products LN Engineering

The down side to the spin-on filters is that it makes it harder to check the filter material, as you need to cut the filter can to get to it. That said, I use a spin on filter.

I think the key is to use a quality oil and change it every 5k or less, especially if you see track time or extended periods of high RPM running. My issue started after a cross-country trip with the engine at 3k+ RPM for about 14 hours each way.
