As their name suggests, cold air intakes bring cooler air into your engine and combustion chamber. In doing so, cold air intakes boost engine power and efficiency. That's because colder air has a higher oxygen density. More oxygen is included in a given volume of cold air than a given volume of warm or hot air. The model can be scaled in order to fit your needs. Along with the native Solidworks file, you can also find parasolid, iges and step formats as well as stl, amf and 3mf. Polygon file is also attached. Can be used for 3D printing.
