Product Description

Heater Plenum for all 1965-1966 Mustangs and 1967-1968 Mustangs without Air Conditioning.

If you're worried about the heat or defrost in your 1965-1968 Mustang without air conditioning, than take a few minutes to replace your heater plenum with this upgraded part from CJ Pony Parts!

Heater Plenum Features and Benefits:
- Direct-fit reproduction of factory original
- ABS plastic material for enhanced durability
- Includes flapper door
- Cable clamp and screw already attached
- Inner door already has closed cell foam bumpers installed

Heater Plenum 1965-1968 is rated 4.6 out of 5 by 21.
Rated 5 out of 5 by from Small, seemingly insignificant part -- NOT! I was desperate to restore heat to my beloved '66 convertible, with cooler days coming. I ordered the heater core and set about getting the hot air flowing. Then, I saw the existing heater plenum - cardboard! It was ratty, ripped, and almost non-functional. If you are restoring your heating system, BUY THIS. It's a cinch to install (much easier while you have the heater box out...I found out the hard way) and the flaps that control defrost and heat function much better within the rigid ABS frame. DO IT!

Rated 5 out of 5 by from excellent fit My heater plenum was broke where cable was located. New one is better material (plastic) unlike the cardboard type of material original is made from.

Rated 5 out of 5 by from Heater Plenum Great replacement for the OEM Plenum by far. Have thought of drilling some holes on the end to let air flow towards my feet also not just the seat.
