  • Installation Guide 

The SF Air Box 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 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.

Cobb SF Intake Airbox

I initially bought the SF intake by itself but quickly seen how hot the intake gets during heatsoak. I ended up buying and installing the airbox and noticed my IATs go down by alot. It does require some more insulation since the box is metal but it still works really good. Personal preference was buying thermal reflective material and covering the airbox to provide more thermal protection.
