This AMR Performance Turbo Inlet is designed it to fit the OEM inlet sized turbos as well as turbos with a 3" inlet.
The cast aluminum this inlet is made of disperses heat better than the stainless steel used in other inlet hoses. Being a cast part it means what you receive will be exactly what they made, where as with other inlets they weld multiple parts together to form the inlet. Where there is welding involved there is room for mistakes.
It is finished in a wrinkle red finish to give it the factory look.
