WHAT IS IT & WHEN DO I NEED IT?

3MI Racing AOS to EJ Turbo Drain Hose Kit Subaru WRX 2002-2014 / STI 2004-2021

INSTALLATION NOTES:

This barb is replacing the provided "Y" fitting that comes with the mentioned AOS kits. The AOS drain barb (located at the bottom of the can) will now be connected to the 1/2 portion of the 3MI Racing drain hose. The 5/8 hose (the lowest and largest port on the side of the AOS can in IAG's case) will now go directly into the top of the center block vent. The hose size must convert from 5/8 to 7/8. That's where our 3MI adapter comes in!

Features:

This fitting is used to adapt IAG Street, IAG Comp, Cobb, and Crawford AOS kits to the 3MI Racing AOS to EJ Turbo Drain House Kit.
