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

Overview

The Perrin Air Oil Separator (AOS) is designed to improve the longevity and performance of your Subaru Legacy XT or Outback XT by effectively removing oil vapors from crankcase gases before they enter the intake manifold. This process reduces carbon buildup on intake valves, a common issue in direct-injection engines, helping maintain optimal engine efficiency and reliability. Ideal for Subaru enthusiasts focused on preserving engine health and performance, the Perrin AOS is a practical upgrade for daily drivers and spirited drivers alike.

Engineered with precision, the Perrin Air Oil Separator features a ceramic-coated, CNC-machined aluminum housing that resists corrosion and heat while ensuring durability. The ceramic coating enhances the separator’s ability to trap oil particles, preventing them from recirculating into the intake tract. Perrin’s commitment to quality and fitment ensures this component integrates seamlessly with the 2020-2025 Legacy XT and Outback XT platforms, reflecting a design philosophy centered on reliability and performance.

By reducing oil vapor contamination in the intake system, this separator helps maintain cleaner intake valves, which translates to more consistent combustion and sustained power delivery over time. For Subaru owners, this means fewer maintenance concerns related to carbon buildup and a healthier engine environment, especially important for turbocharged models like the Legacy XT and Outback XT. The Perrin AOS is a straightforward yet effective solution to a common Subaru engine issue.
