The cores are a nylon plastic that is stronger than the metal cores. In the early days of ecores there were problems with the plastic cores of that time and also with media failures do to being pulled through the plastic cages.Thank you for capturing and showcasing this filter.
Is this embarrassing to have an ecore filter on a 80-100k SUV from the factory? Or is it a non-issue? I'm not high class enough to know.
They have long since addressed the problems.
I use them almost exclusively on my spin on applications and they are always perfect when I chop them open to see
