2022 -2024 Subaru WRX
Features:
The Killer B Motorsport Performance 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. This is accomplished by using a vortex system that is efficient without limiting flowrates, unlike baffled units.
Killer B's Performance Dual AOS configuration places the AOS on the firewall and in front of the intake manifold.
Pretty straight forward to install. Would recommend getting a long needle nose pliers and an adjustable 7mm ratchet and socket to complete the job.
Easy install for good price.
Straight forward installation except application was for 23 Wilderness. Slightly modified installation to firewall catch can. Currently and temporarily secured to ABS line until strut tower bracket is fabricated.
