The Killer B Motorsport Dual Catch Can AOS system is designed to remove excess oil vapor from crankcase gasses before they reach your intake. Doing so keeps your intake and valves cleaner and maintains proper octane levels. We do this using a vortex system that is efficient without limiting flowrates, unlike baffled units.

Our Performance Dual AOS configuration places the AOS's on the firewall and in front of the intake manifold.
