i was changing my oil today. i bought a filter from the internet (sad to admit..ebay). when i removed the old filter, the new one didn't fit. the inner opening was too small on the new one. i specifically ordered a filter that supposedly fit the boxster. figured i made a mistake by buying it on ebay, i went to autozone and bought another one. however, when i got home, i realized i had the same problem. the dealership was already closed so i just reused the old filter. but has this happened to anyone else? i normally buy it from suncoast or dealer..now learned my lesson.
