That's what wide pleat spacing will do, doesn't matter the brand. For a 15k rated filter at a bit over a third of that, tear or not, not exactly confidence inspiring. If it didn't tear, best can be said, it survived. Wonder what it would have looked like at even 7500 miles.
To my eye looks like skimpy media area. I've seen other brands here flogged for less.
Thanks for c&p.
