Mustang Heater Core Flow Restrictor
The heater core flow restrictor is an important part in the replacement of your heater supply hose and heater core on your 1979-2004 Mustang. This part helps reduce the risk of your heater core failing. The flow restrictor's job is to decrease the pressure of the coolant that flows into the heater core. This heater hose restrictor is original equipment on 1996-04 Mustangs, but can also be used on 1979-95 Mustangs as well.

Installation Note
Because of it's slightly longer length, light grease may be required to fully insert the restrictor into the 79-95 heater hose.
