Cobb Tuning Big SF Intake System Subaru 2015-2021 WRX
COBB Tuning Subaru Big SF Intake System The Big SF Intake for the 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 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!
Note: Proper tuning is MANDATORY for this intake!! Use associated +BigSF OTS Maps or have your car tuned by a certified protuner.
