Crawford Air Oil Separator Complete Install Kits

For those of you who have purchased one of our Air/Oil Separators used, or just want to refresh your current kit, here are all of the pieces for re-installation. Pieces and prices will vary for each application.

Need help identifying which full kit part number is meant for your canister or vehicle?

Below are the full kits listed based on the canister type. If your vehicle is not listed with the canister, then that means that the canister you have is meant to be mounted on a different vehicle or location. That being said, you may be able to retrofit the unit to your engine bay: just be sure to mount the canister so that the ports are higher than their connection points. 

Do you have the wrong canister for your vehicle or do you need to mount it in a different location?

This only applies to the V2 cans (6 port), but you can cut off the bracket and purchase the Universal Kit (S0712-1). It comes with 3 different brackets to choose from along with a clamp for holding it to the canister. If you don't want the look of a clamp around your canister, you can take your bracket of choice to a fab shop to have it welded on.

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.
