AOS Drain Kit - Subaru EJ 2.5L Motors

Overview

This optional drain kit for the Verus Engineering air oil separator on Subaru EJ 2.5L engines returns oil caught in the separator automatically to the engine. That removes any need to open or drain the unit, so it provides maintenance-free oil separation for years.

It includes CNC machined and anodized aluminum fittings and 1/2-inch rubber hose. The separator already works as a typical drain-style unit without it, so it is only needed by owners who want this function.
