DETAILS:
Perrin Air Oil Separator V2 Black 2002-2021 WRX / 2004-2021 STi | Ceramic-Coated CNC Machined | Engine Health Component
Overview
The Perrin Air Oil Separator (AOS) V2 is a precision-engineered solution designed to capture oil vapors from the crankcase gases before they reach the intake manifold on Subaru WRX and WRX STI models spanning 2002 to 2021. By efficiently separating oil from the blow-by gases, this component helps prevent carbon buildup inside the intake tract, a common issue that can compromise engine performance and longevity. This product is ideal for Subaru enthusiasts who prioritize engine cleanliness and reliability, especially those with modified or high-mileage engines seeking to maintain optimal running conditions.
Crafted with a ceramic-coated, CNC-machined aluminum body, the Perrin AOS combines durability with functional design. The ceramic coating reduces oil adhesion inside the separator, enhancing its efficiency and resistance to corrosion. Perrin’s approach emphasizes robust construction and precise fitment, ensuring that the AOS integrates seamlessly with Subaru’s PCV system while delivering consistent performance benefits.
Installing the Perrin Air Oil Separator offers tangible advantages such as reduced intake manifold contamination, improved throttle response, and potentially extended engine life by minimizing harmful oil vapor ingestion. For WRX and STI owners, this means less frequent intake cleaning, better engine health, and a more reliable driving experience whether on the street or during spirited driving sessions.
