The AWE Tuning S-FLO breather filter is the small auxiliary filter needed with some AWE intake installs on VW and Audi 2.0T engines. When a Secondary Air Injection (SAI) hose is present, this breather becomes a required accessory to complete the intake routing and protect the system. It’s intended to pair with AWE intakes and the product imagery helps identify SAI hose locations for proper installation.
