Each engine vent port receives its own connection to the AOS. By giving each engine port its own entrance to the AOS we have allowed for more effective and faster excavation of crankcase pressure. Additionally, this reduces overall system pressure. With a 4\" OD and 5.75\" height, the AOS has an approximate 1 liter of holding capacity. The larger the AOS, the more power you can safely make without having to worry about the AOS overfilling.\u003c\/span\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp class=\"accordion--simple__article\"\u003e\u003cspan data-mce-fragment=\"1\"\u003eThe bottom of the AOS is shaped like a snail, redirecting positive crank pressure into the same swirl pattern produced by the 3 side ports.

This maximizes the evaporation of any water collecting inside of the can.
