About this part
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
Note: You will need the Cam Block Off Plate (PN A0011A) for it to fully function, which is shown below.
SCIENCE
Our AOS has one job and that is to remove the oil from the engine crankcase system so the oil does not get into the intake system. Oil in the system reduces octane, which can lead to detonation, reduction in power, and carbon build-up.
