Crawford Air Oil Separator Baja - 2019+ Forester 2.5 and Wilderness

The Crawford Air Oil Separator Baja is an essential component for the 2019+ Forester 2.5 engine. It is designed to improve engine performance and longevity by reducing the amount of oil vapors that enter the engine's intake system. This innovative product is the result of years of research and development by the experts at Crawford Performance.

The Air Oil Separator works by capturing the oil vapors that are released from the engine's crankcase. These vapors are then sent through a series of baffles that separate the oil from the air. The oil is then returned to the engine's crankcase, while the clean air is sent to the engine's intake system. This process significantly reduces the amount of oil that enters the engine's intake system, which can improve engine performance and reduce the risk of engine damage.

The Crawford Air Oil Separator Baja is specifically designed for the 2019+ Forester 2.5 and is made from high-quality materials to ensure durability and reliability. With easy installation, this product is a must-have for any 2019+ Forester 2.5 owner looking to improve engine performance and longevity.

The Crawford Performance Air Oil Separator (AOS) is the original solution to Subaru's notorious oiling system issues. Although the technology was pre-existing with other vehicle brands such as Porsche, Crawford Performance is the inventor of the first system specifically for Subaru. No other AOS on the market employs the same technology.
