Fitment Information:
2015-2021 Subaru WRX
Features:
The COBB SF Intake System is our entry level intake upgrade for your 2015-2021 WRX.
Replacing the factory intake and airbox with the COBB SF Intake will 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!
Construction
The airbox is constructed of black powder coated aluminum. A slot in the front of the airbox accepts air directed through the factory air scoop. Air is filtered through a larger pre-oiled filter and routed to the velocity stack MAF housing. The wire-reinforced black silicone couplers are sealed on either end with clamps for a leak-free install.
Velocity Stack MAF Housing
This intake system utilizes several unique features in an effort to maintain optimal flow for performance while minimizing turbulence. A custom conical air-filter element, CFD-designed velocity stack and unique air flow straightener grid are designed to smooth the incoming air flow as it passes the Mass Air Flow sensor for precise readings. The one piece high temperature plastic composite design saves weight and reduces heat transfer.
Calibration
The SF Intake System is compatible with COBB Off The Shelf Maps. Look for maps denoted with "+SF" in your Accessport firmware.

This video should help you decide if you want this one or a different one! Running a turboXs dp and it sounds amazing. Heard the big SF was giving people issues so decided to buy this one, so far so good. No leaks or nothing.
Waiting on a few more parts to install this but it came packed well and build quality looks A+
Great product helped reduce intake temps and looks great under the hood. Cobb as always a reliable product.
Install was straight forward with video. Packaged well and shipped quickly. No damage upon arrival. No missing components or any other issues or concerns. Recommend for those subie moans
