Perrin Air Oil Separator Black 2022-2025 WRX | Ceramic-Coated CNC Machined | Engine Health & Oil Vapor Separation Overview The Perrin Air Oil Separator (AOS) is designed specifically for the 2022-2025 Subaru WRX to effectively remove oil vapors from crankcase gases before they enter the intake manifold. By separating these oil vapors, the AOS helps reduce carbon buildup on intake valves and maintains cleaner combustion chambers, which is critical for direct-injection engines like the WRX. This part is ideal for Subaru enthusiasts looking to improve engine longevity and maintain peak performance. Engineered with precision, the Perrin AOS features a ceramic-coated, CNC-machined aluminum housing that ensures durability and resistance to corrosion. The ceramic coating not only enhances longevity but also aids in heat dissipation, contributing to more efficient vapor separation. Perrin’s commitment to quality and fitment ensures this AOS integrates seamlessly with the WRX’s factory PCV system without requiring modifications. For Subaru owners, this Air Oil Separator offers tangible benefits by reducing oil contamination in the intake tract, which can lead to smoother idle, improved throttle response, and reduced maintenance intervals related to carbon cleaning. Maintaining a cleaner intake environment supports the WRX’s turbocharged engine health, especially under spirited driving or track conditions where blow-by gases increase.
