DSMLVR - very good explanation.

The breathers keep hot air out of yru intake and dirty air out of yoru intake. So the cooler air you can bretah in the better. The other source of the hot dirty air enetring yoru intake is... the EGR System (Exhaust Gas Recirculation) This is what really gunks up the intake manifold, which with restrict air flow and reduce the power and efficiency of your manifold, especially if you have a ported/polished intake panifold.
