Verus Engineering AOS Kit - 2015-2021 Subaru WRX

Ultimately it is designed to perform the crucial task of eliminating oil from the engine's crankcase system. This is to ensure that the oil does not infiltrate the intake system, causing a decrease in octane, which can lead to a series of problems, including carbon build-up, power reduction, and internal engine damage. With the aid of coalescent filters, oil vapor with a size as small as 5 microns can be effectively filtered out.

KEEP THE INTAKE IN YOUR VA WRX FREE OF HARMFUL OIL VAPORS

The Verus Engineering Air Oil Separator (AOS) guarantees that oil is prevented from entering the intake system. The existence of oil in the system has the potential to reduce the octane level, which can result in problems such as detonation, power reduction, and carbon accumulation. It is possible to install the unit without necessitating any adjustments to the tune or setup. The Verus AOS provides excellent air filtration for the crankcase air, using four, 5-micron, coalescent filters, baffling, and stainless mesh. Furthermore, It filters both the crankcase vent location and the intake filter location via a single unit. During colder months, you may utilize the optional coolant hook-up kit to direct hot coolant through the AOS and minimize condensation accumulation.
