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). This kit includes a zinc-plated steel plug with an o-ring seal retained by a bracket and bolt.
