Verus Engineering AOS Drain Kit - 2013-2020 Subaru BRZ/Scion FR-S/Toyota GT86 (ZC6/ZN6)

By using our add-on AOS Drain Kit, the AOS can be used for years of service-free life. 

No need to drain, open it up, or do anything but drive the car!  This is optional, only those that want this function should purchase this add-on. The AOS works like a typical drain style unit out of the box.

Note: You will need the cam block off plate (PN A0011A) for it to fully function, which is shown below.

WHAT IS INCLUDED:

• One Way Check Valve

• Pre-Assembled Push-Lok Hose with 6an Fittings

• O-Ring
