Cobb Air Box For SF Intake 2015-2021 STI

Add to your SF intake for a complete cold-air system!  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.

The Cobb SF 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.

Just to be clear, this is NOT a complete intake system. It’s an add-on for a Cobb SF intake, which is sold separately.

For 2015-2021 WRX STI only.  Does NOT fit 2015+ WRX.
