Setting the standard for MAF style intakes with a velocity stack, airflow straighteners and composite body for ultimate performance. Feed your SF Intake cold air using the Subaru factory snorkel. The SF Airbox turns your SF Intake on your STI into a cold air intake with OEM looks and fit.

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.

  • Composite Intake Body for Heat Rejection
  • Integrated Velocity Stack & Airflow Straighteners
  • Pre-Oiled, Cleanable, Reusable Custom Filter Element
  • Uses Factory Snorkel to Feed Cold Air to Airbox
  • Benefits of CAI without Water Ingestion Issues

The main thing my car was lacking was turbo noises, and this intake fixed that issue and exceeded my expectations on how great my car sounds now. Install took maybe 20 minutes with zero fitment issues and the Cobb stage 1+ map with this intake really woke the car up. Very happy with my purchase!

Best Intake Ever!

What can I say about this intake. It blew me away! The sound is innnsaaannnne!!! The power gain is real!!! Get one, don’t hesitate!!!


Thank you for the 5 Star Review and added Pic! The COBB SF Intake+ Airbox Combo is the perfect way to get direct cold air into your engine! The aluminum intake airbox is specifically designed to block out the hot air in the engine and to accept the OEM snorkel creating a factory look. It sounds great and adds plenty of performance!
