It allows the engine to evacuate internal pressure on its own without using the intake stream to do it. It also catches any oil which might come out of those lines which is required by many racing venues to prevent oil downs/wrecks. It allows the engine to suck fresh air, it also allows internal engine breathing on a turbocharged application as when you have boost in the intake manifold the one way check valve off the block does not allow any air to flow, thus backing the engine up at the point of the most blow by. It also adds some bling bling to your engine bay
