k&n oil filter
 

Has anyone had any experience with the k&n hp7011 oil filter on their boxster?

Well, I tried one and the visual inspection of the used filter seemed to indicate that the filter was performing as well as the Hengst. I saw about the same amount of tiny non-magnetic dots and small brown plastic-like particles. My magnetic oil plug had about the same amount of ferrous sludge on it. I'd use them.

I've used them a couple of times, no complaints:)
