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 Street Single AOS configuration places the AOS behind the intake manifold. This setup is intended for high performance street use.
