COBB SF Blue Intake + Airbox Combo 2019-2021 STI / 2018 STI Type RA

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.
