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.

AIRBOX

The 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.

FEATURES:

• 16 Gauge Aluminum Construction
• Uses Factory Snorkel to Feed Cold Air to Airbox
• Benefits of CAI without Water Ingestion Issues
• Easy Installation
• OEM Quality Fit and Finish

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.

INTAKE

The COBB Tuning SF Intake removes a pre-turbo restriction in the stock intake system. The SF Intake intake system utilizes several unique features in an effort to maintain optimal flow for performance while minimizing turbulence that can cause engine management problems.

From a custom conical cloth air-filter element, a CFD-designed velocity stack leads to a unique airflow straightener grid designed to smooth the incoming air flow as it passes the Mass Air Flow sensor for precise readings. The intake utilizes a one-piece design constructed from a high-temperature plastic composite, saving weight and reducing heat transfer.

FEATURES:

• Composite Intake Body for Heat Rejection
• Integrated Velocity Stack
• Integrated Airflow Straighteners
• Blue 4-ply Steel Reinforced Silicone Post-MAF
• Induction and Engine Sounds More Audible
