I found the same things.quote:
I will also say that in cutting one of the E-Cores open, I was certainly surprised by how well the fiber end caps were attached with the bonding process. I would have expected them to peel right off, but it took quite a bit of force to remove it. Also, the plastic core was very strong as well.
I tore one open after reading everyone poo pooing the Ecore.
They have never used one, they have never opened one, but it' a "cheap filter that will kill your motor" bravo sierra comes out of their mouth.
So, I went a cut one open. Very impressed.
I've used about 2 dozen now in many cars/trucks and all have been perfect.
I cut open every filter I use and not a single issue.

Thanks Filter Guy for the ink description and how that works.

Take care, Bill
