Reading about the recent P1 torn media posts, I went out and cut open a couple of Bosch Premiums that I hadn't yet pitched.
This filter was in service for 6,372 miles.
The pleat to the left of the seam is torn on the opposite end as well.
Date Code:
I also cut open a Bosch Premium 3331 that was in service for 7,462 miles that is date coded F11B15B2. The media in this filter was intact. This filter also did not have the metal seam joint/re-enforcement.
