Air Horn Assembly for 2008-2010 6.4 Truck with 2003-2006 Cummins (5.9 Only)

This air horn is very helpful to make intercooler plumbing easier by allowing you to utilize your driver's side intercooler tube. Includes the required spacer, and a custom pipe bushing for installing your Ford MAP sensor so the boost gauge in your dash will work. *Does not work with 6.7L Cummins engines*
