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 filter can be cleaned and re-used for the life of your vehicle.
Note: Proper tuning is MANDATORY for this intake!! Use associated +BigSF OTS Maps or have your car custom tuned.
