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!

*NOT CARB Compliant* Shipping to California is restricted due to not being CARB compliant.



The Big SF Intake for the 2015‐2016 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!

Note: Proper tuning is REQUIRED for this intake!! Use associated +BigSF OTS Maps or have your car tuned by a Certified Protuner

  1. Quality Product

    By Anthony April 29, 2017

    COBB can be counted onto have quality product! I purchased this along with the Ethanol Kit and J-Pipe! Installation was pretty straight forward and took just around an hour and a half.

    The Fitment was near perfect and leaves the car with a factory looking intake. However once you get on the throttle and around 3000 rpm's you can hear the intake going to work and the turbo spool. Gives it a slightly more aggressive sound when you are getting on the throttle. Still sounds stock when you aren't. Can't go wrong with this intake system!

    NOTICE: It is required to have a tune once you install this product. Maps can be found on COBBs site or go to a protuner.

  2. Nice
