PERRIN Air Oil Separator - Red - 2013-2016 Scion FR-S / 2013-2026 Subaru BRZ / 2017-2026 Toyota GR86 / 86

PSP-ENG-624RD

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 process reduces carbon buildup on intake valves and combustion chambers, which is a common issue in direct-injection engines. Ideal for enthusiasts who want to maintain engine cleanliness and optimize performance, the Perrin AOS is a practical upgrade for daily drivers and track-focused builds alike.

Crafted with precision, the Perrin Air Oil Separator features a ceramic-coated, CNC-machined aluminum housing that ensures durability and efficient vapor separation. The ceramic coating not only enhances corrosion resistance but also helps prevent oil from sticking to internal surfaces, maintaining optimal function over time. Perrin’s engineering approach focuses on reliability and fitment, delivering a product that integrates seamlessly with the BRZ/FRS/86 platform without compromising OEM quality or requiring extensive modifications.

By diverting oil vapors away from the intake tract, this separator helps preserve engine health and reduces the need for frequent intake cleaning. For Subaru BRZ owners, this means a cleaner combustion process and more consistent performance. The red finish adds a subtle visual upgrade under the hood, complementing other performance parts. Overall, the Perrin Air Oil Separator is a smart investment for Subaru enthusiasts seeking to protect their engine while maintaining the car’s factory drivability and responsiveness.
