Bump from the dead, I know. But I'm researching air filters.

Just to put things into perspective for those that get super excited over numbers but have no idea what UNITS those numbers are in...

1 inch (of H20) pressure drop due to a reported 60 (or 20, whatever) grams of dust correlates to a .036 psi of resistance. Yeah, that's zero point ZERO three six pounds per square inch... That means your turbo has to work 0.036 psi harder... OH NOES! THE WORLD WILL END!
