I'm just curious, guys, now that thread drift has taken the discussion to CFM for various filters.
Seeing as K&N makes 9" diameter filters in various thicknesses, would you think that the greater CFM would come from the thicker filters (2") or the thinner filters (1"). There is also a 1.5" to muddy up the waters even more.
It seems to me that the thicker filter, the 2", would have deeper pleats in the filter material, yielding greater filter area. That seems to me to provide an advantage in CFM...anyone have any ideas? For right now it's just one old retired schoolteacher type postulating.....or is that hypothesizing.....or......well, anyway.....
