The COBB SF Intake System is our entry level intake upgrade for your 2015-2021 Subaru WRX .

The air box is constructed of black powder coated aluminum. A slot in the front of the air box 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.

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.


The SF Intake System is compatible with COBB Off The Shelf Maps. Look for maps denoted with "+SF" in your Accessport firmware or on the Maps section of the Cobb website. For a complete list of maps for your car, head over to the Maps Section of the Cobb website.


  • Integrated Velocity Stack MAF Housing

Great product

It was easy to install. Sounds great and with the tune it opened up the car.

Whoosh Noises!

This thing is great. Got it installed in an afternoon, flash-tuned it with the Accessport, and got to hear "pshh" noises from my stock bypass valve that I couldn't hear before. Induction noises are also much louder, overall incredible sound. Also, Cobb completely overhauled this intake, old versions caused a lot of AF Ratio issues since they required you to place the air filter in a very specific spot to work correctly. On this version, there's a hard plastic stop to push against that eliminates that problem entirely.


We appreciate your 5 Star Review of the COBB SF Intake System designed for the 2015-2021 WRX. We are delighted to hear that the installation process went smoothly for you, and the flash tuning with the Accessport resulted in the delightful 'pshh' noises from the stock bypass valve, as well as louder induction sounds. Your satisfaction with the improved design, particularly the hard plastic stop that ensures correct air filter placement and eliminates issues with the air-fuel ratio, is valuable feedback. Enjoy your added sound and performance!
