Perrin Air Oil Separator Red 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 improve engine longevity by effectively separating oil vapors from crankcase gases before they enter the intake manifold. By capturing these oil vapors, the AOS prevents carbon buildup inside the intake tract, which is a common issue that can degrade performance and increase maintenance needs. This part is ideal for Subaru enthusiasts looking to maintain a clean intake system and support long-term engine health, especially those who drive their WRX aggressively or have modified engines.
Engineered with precision, the Perrin AOS features a ceramic-coated, CNC-machined aluminum body that ensures durability and resistance to heat and corrosion. The ceramic coating not only protects the unit but also aids in reducing oil adhesion inside the separator, enhancing its efficiency. Perrin’s design philosophy focuses on combining high-quality materials with functional engineering to deliver reliable performance upgrades that integrate seamlessly with Subaru’s boxer engine architecture.
Installing the Perrin Air Oil Separator offers tangible benefits such as reduced intake manifold contamination, which helps maintain consistent airflow and combustion efficiency. This translates to more reliable power delivery and less frequent intake cleaning for WRX owners. Its direct fitment and robust construction make it a practical upgrade for daily drivers and track enthusiasts alike, preserving the performance potential of your Subaru WRX while safeguarding its engine components.
