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
