Looking to improve your factory air intake while still retaining the sealed factory air box on your 6.7L Cummins? Check out the new intake system from Performance Systems Manufacturing (PSM). The Cool Power cold air duct delivers cold air to the bottom of the OEM air box while the silicone rubber Cool Hose duct assures the air going to the turbo is unrestricted and kept as cool as possible, allowing for more power and lower egts.
