This direct-fit replacement heater plenum is molded from new ABS plastic for improved durability over the factory cardboard plenum.

The best and easiest time for this plenum to be installed is when you're already working on your heater box--this will add just a few extra minutes to overall installation time but will provide a dramatic improvement.

Please Note: This heater plenum will fit all 1965-1966 Mustangs as well as all 1967-1968 Mustangs without air conditioning.
