The Subaru STI Air Oil Separator by Perrin Performance is the perfect upgrade for your '04-'21 Subaru WRX or STI. Crafted in sleek black, this essential component works to separate oil from the air circulating within the engine, thereby enhancing overall engine performance and longevity.

The Perrin Performance Air Oil Separator effectively traps this unwanted oil and keeps it separated, ensuring your vehicle runs smoothly and efficiently. This component is especially beneficial under high-performance driving conditions, as it can prevent oil buildup in the intake system, leading to improved horsepower and engine efficiency.
