AOS Drain Kit - 2022+ Subaru BRZ/Toyota GR86/VB Subaru WRX

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.

Manual transmission fitment only. Will not work with automatic transmissions
