I got 2 of the "defective" bosch filters from rockauto, and this is the first one i used. It was in service for 3500 miles with qsfs 10w30. No metal as far as I can tell, and no oil starvation noises. I put the other filter on but I'm not buying these again, because even though I don't think it'll hurt anything, I don't like how small the holes are.
Forgot to take pictures of the louvers
It seems to have caught a significant amount of carbon in the filter even though it's clean under the valve covers. No sparkles, otherwise I would have tossed the second filter. Will these chunkies hurt anything? They're just mushy carbon as far as I can tell.
What do y'all think? Current fill is ceratec + 5w40 euro Quaker State. I'll probably change it again in like 2 years or 3000 miles.
These filters didn't have metal shavings in them when I opened them, like the bosch filters in that other recent thread
