Perrin Air Oil Separator V2 Red 2022-2025 Legacy XT / Outback XT | Ceramic-Coated CNC Machined | Engine Health Accessory
Overview
The Perrin Air Oil Separator (AOS) V2 is a precision-engineered solution designed to improve engine health by efficiently separating oil vapors from crankcase gases before they reach the intake manifold on 2022-2025 Subaru Legacy XT and Outback XT models. This vital component helps prevent carbon buildup inside the intake tract, a common issue that can degrade engine performance and reduce longevity. Ideal for Subaru enthusiasts who prioritize maintaining a clean intake system and supporting long-term engine reliability, the Perrin AOS is especially beneficial for those who engage in spirited driving or extended highway use.
Built with a ceramic-coated, CNC-machined aluminum housing, the Perrin AOS combines durability with functional design. The ceramic coating enhances corrosion resistance and reduces oil adhesion, improving the separator’s efficiency and lifespan. Perrin’s engineering approach focuses on seamless integration with the Subaru boxer engine’s ventilation system, ensuring reliable operation without compromising factory fitment or requiring modifications.
For Legacy XT and Outback XT owners, this air oil separator delivers real-world benefits such as reduced intake manifold contamination and lower oil consumption. This translates to cleaner combustion chambers, improved throttle response, and more consistent engine performance over time. The red anodized finish also adds a subtle yet refined visual upgrade under the hood, reflecting Perrin’s commitment to quality and attention to detail that Subaru enthusiasts expect.
