Skunk2’s Cold-Air Intake is manufactured from molded polymer plastic for superior intake air insulation when compared to aluminum as well as for a smooth, continuous taper. When compared to aluminum, the thicker polymer material results in a superior thermal barrier and lower intake air temperatures drastically reducing heat soak in comparison to other intakes. For optimal power, the BRZ/FRS Cold Air Intake draws in the coldest and highest pressure air available. This is achieved by placing the Ram Air Box’s inlet duct in front of the radiator where the most clean and cold air is found. The Ram Air Box is manufactured from crosslinked polymer to provide superior thermal rejection and structural strength as the air filter’s housing. Skunk2 Cold Air Intake systems for the BRZ/FRS include a Skunk2 Composite Velocity Stack which is a $50 added value. The Composite Velocity Stack utilizes race proven technology and is engineered to optimize air flow while maximizing velocity. The glass fiber nylon structure imparts high impact strength with low thermal conductivity to significantly reduce heat soak and air intake temperatures. The design also incorporates dimples on the entry surface to extend the boundary layer into the mouth. The dimples increase the effective cross sectional flow area causing higher total mass air flow compared to other velocity stacks. The Throttle Body Velocity Tube is manufactured from crosslinked polymer for thermal isolation which again reduces heat and heat soak. It also features a smooth, continuous flow velocity taper from 96 mm internal diameter to 70m mm internal diameter which allows high air flow ultimately producing one of the best flowing and filtered Cold Air Intakes for the BRZ/FRS. It connects to the factory throttle body, no cutting or fabrication needed as it is a direct bolt on application.
