you know that is a good question, that I have an opinion on. The surface area limitations of the aftermarket elements, demands porosity. The more air that you want to move, the harder the turbo pulls on any contaminates that can come through...and they do come through. This is NEVER tested in reality. What you do see frequently claimed, is the pressure drop of the (new) element under these high flow conditions. No mention of filtration efficiency.
If longevity simply has no value, then use whatever you want...or no filter for that matter. If you get an ET change, let us know, but I doubt you will.
The stock 1618C element has more surface area than the hood itself, and even at 500 HP, air has an average velocity of 3 mph across it, slow enough to avoid this "pull through".
What is really impressive, is the comparison between a "dirty" stock element and a dirty aftermarket element. The stock has lots less resistance. The aftermarket is polluting the charge with contaminants.
Have heard of some of these elements collapsing under the Hoovers pull.
But cleaning an element is fun I have heard. I'm lazy:baby:
