The Big SF Intake for the 2015‐2017 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 Subaru.
Replacing the factory intake and airbox with the COBB Intake will greatly reduce pre‐turborestrictions. When a restriction is removed, it allowsthe engine to be more efficient while also enabling itto make more power.
Note: Proper tuning is REQUIRED for this intake!! Use associated +BigSF OTS Maps or a tune by a Certified Protuner.
