Found in oil filter

[matao87]

First oil change after purchasing my 98 boxster and found two metal flakes and what appears to be 3 plastic pieces in the filter. The metal pieces appear to be non-ferrous metal as I could not get a strong magnet to pick them up even after careful cleaning to remove oil. From my research it appears that ims bearing material should be magnetic. Should I worry about a couple flakes at 89k miles? The plastic appeared to be brown color so in guessing chain guides...
