Some engine swaps and racing applications do not need the heater, but it is tough to block off with the 7.3-liter Godzilla engine. The factory rear hose port is retained with a bolt (and the port is not tapped), and the front port is a tube with a hose barb that isn't removable. This kit includes a billet plug with an o-ring seal retained by a bracket and bolt, and the second plug is a rubber cap with a billet cover that clamps over the tube. These caps and plugs provide a more attractive appearance than other options.

Features:

• Ideal for use in engine swaps or racing applications that do not require a heater
• Note: The 7.3L engine design does not require a loop between the heater outlet and inlet. It is safe to block both ports off.
