This is a pretty massive failure. The filter media could possibly have passed through the holes and gotten into the engine internals.
At least that is one good thing about louvers.

While this is true, we see too many Puro made filters with failures within recommended intervals to say it is just a fluke.
How many other brands do we see that have gone beyond their recommended interval still intact, as well as intact for normal intervals?
Aside from a few manufacture defects (the Fram missing 1/3 of the media and the Wix with pleats not glued), failures like this are not common, except on Puro filters (and the one
Champ made that THafeez posted today with unknown details).
