Perrin Air Oil Separator Red 2022-2025 Legacy XT / Outback XT | Ceramic-Coated CNC Machined | Engine Health Accessory

Overview

The Perrin Air Oil Separator (AOS) is designed to efficiently remove oil vapors from the crankcase gases before they enter the intake manifold on 2022-2025 Subaru Legacy XT and Outback XT models. By capturing these oil vapors, the AOS helps prevent carbon buildup inside the intake tract, which can degrade engine performance and longevity. This component is ideal for Subaru owners looking to maintain a cleaner intake system and support long-term engine health, especially under spirited driving conditions.

Engineered with precision, the Perrin AOS features a ceramic-coated, CNC-machined aluminum housing that offers superior durability and corrosion resistance. The ceramic coating not only protects the unit but also aids in reducing oil adhesion, enhancing the separator’s efficiency. Perrin’s design philosophy focuses on combining robust construction with functional performance, ensuring that this AOS integrates seamlessly with the Subaru boxer engine’s ventilation system without compromising reliability.

For Subaru Legacy XT and Outback XT owners, this air oil separator provides tangible benefits by reducing intake manifold contamination and oil consumption. This leads to cleaner combustion chambers, improved throttle response, and a more consistent engine operation over time. The red anodized finish adds a subtle visual upgrade under the hood, reflecting the quality and attention to detail that Subaru enthusiasts expect from Perrin Performance.
