Where does the dirt come from? Do some people leave out their air filter or can leaks develop in the induction tract, after the filter?

Hi Trev. the dirt doesn't come through the air intake. It comes from the exhaust gas re circulation valve, and the crankcase ventilation valve, It is moved back and forth to the throttle body, by the pressure waves that operate there.
