  • The Big SF Intake for the 2015+ Subaru WRX is constructed of full 3" aluminum tubing, a custom aluminum airbox, and a dual cone intake filter. Mandrel bent and powder-coated black, the 3" intake tube and custom airbox look great in the engine bay and increase airflow potential substantially. The reusable green filter can be cleaned and re-used for the life of your vehicle! 

    Replacing the factory intake and airbox with the Cobb Big SF cold air Intake will greatly reduce pre-turbo restrictions. When a restriction is removed, it allows the engine to be more efficient while also enabling it to make more power!


    • Black 3" Mandrel Bent Aluminum Tubing
    • Black Airbox with Laser Etched Logo
    • Dual Cone, Pre-Oiled, Green Filter
    • Plug & Play MAF Extension Harness

    Proper tuning is MANDATORY for this intake!! Use associated Cobb +BigSF Off-The-Shelf (OTS) maps or have your car tuned by a Certified Protuner.
