I have yet to see any element compare to the surface area of the delco element.

With no test data to support a product that claims this or that, I must assume hype is the rule of the day, and often is with these aftermarkets. I would be the first in line to buy it, but not because it has a catchy name. The fiber technology has not changed the simple science behind filtration.

To reduce pressure drop, you must open up the pore size or add more surface area. The type of fiber is irrelevant, they are still just restrictive openings for air to flow through.

If there is a compelling (factual) argument that I am missing, I've yet to hear it. Science is hard to argue with.
