Not sure if this has been covered, but what are everyone's thoughts on the foam filter elements rather than paper or other synthetics?
These filters are "dry" (I.E no oil) and are claimed to flow just as well as any other aftermarket filter, but with much better filtration qualities. And they're washable with soap and water.
I know there's no tangible benefit to installing one of these filters, but I am simply asking for a comparison of one aftermarket type to another, because as far as I've heard, these are the best things in the aftermarket world as far as filters go.
This is one brand. There's a few others out there as well.
