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. The Skunk2 BRZ/FRS Cold Air Intake uses a massive 6.8” diameter double cone filter element which will allow for larger dust holding capacities. The cone filter is also washable which will avoid future expenses on a replacement filter. The supplied MAF Sensor Coupler is compatible with the factory MAF sensor for an easy bolt on application. This is the highest flowing BRZ/FRS intake on the market.
