PERRIN BRZ/FR-S/GR86/86 Air Oil Separator - Black

The Perrin Air Oil Separator (AOS) is designed to improve the longevity and performance of your Subaru BRZ, Scion FRS, or Toyota 86 by effectively removing oil vapors from crankcase gases before they enter the intake manifold. This prevents oil contamination in the intake tract, reducing carbon buildup on intake valves and maintaining cleaner combustion chambers. Ideal for enthusiasts who want to protect their engine while maintaining factory-like reliability, the Perrin AOS is a practical upgrade for daily drivers and performance builds alike. Engineered with precision, the Perrin AOS features a ceramic-coated, CNC-machined aluminum body that resists corrosion and heat while providing superior durability. The ceramic coating enhances oil separation efficiency and simplifies maintenance by preventing oil from sticking to internal surfaces. Perrin’s commitment to quality and fitment ensures this unit integrates seamlessly with the BRZ/FRS/86 platform without compromising OEM reliability or requiring extensive modifications. By reducing oil vapor recirculation, this Air Oil Separator helps maintain optimal engine health and performance over time. Subaru BRZ and Toyota 86 owners will appreciate the cleaner intake system, which supports consistent power delivery and reduces the risk of costly carbon-related issues. This component is a smart preventative measure that complements both stock and modified engines, especially those subjected to spirited driving or track use.
