The SF Airbox adds the benefits of a cold air intake to the outstanding performance of the SF Intake. The factory inlet directs cold air from the front grill to the SF Airbox, which encloses the SF Intake. Hot engine bay air that robs horsepower is prevented from entering the intake system to provide consistent intake performance. This unique design also separates rainwater from the intake air, eliminating the water ingestion issues that plague in-fender cold air intakes.


This SF Airbox Kit includes a New Subaru OEM Air Duct that provides fresh air from behind the grill directly into the airbox. This duct is REQUIRED for compatibility with the 2018 STI Type RA and 2019 STI.

This intake airbox is constructed of 16 gauge aluminum, consisting of a one piece surround, directional lid, stainless steel hardware and all the necessary components for a seamless install with OEM quality fit and finish.

  • 16 Gauge Aluminum Construction
  • Uses Factory Snorkel to Feed Cold Air to Airbox

  • Easy Installation
  • OEM Quality Fit and Finish

    Fitment is good a little tricky but got the air box and oem breather .

    Jimmy,

    We are glad to hear that you were able to get the COBB SF Airbox installed successfully! The improved fitment and use of the OEM breather are essential for optimizing the airflow to your engine, leading to potential performance gains. If you paired it with other performance modifications, you should notice an enhanced driving experience. Thank you for your 5 Star Review and added pic! Happy driving and enjoy your upgraded STI!
