Defrost Plenum
$80 + $10 Shipping
For the Factory Five Mk I, II and III Roadsters
One of the problems with FFR cars and the heater on the passenger side is getting defrost while getting heat to both sides of the passenger compartment. So, if you are tired of all the hoses behind your dash why not run only one hose for your defrost. With this set up run one hose from the defroster to the plenum to get both vents with one hose, then run the other defrost duct to the driver and if the passenger gets cold turn on the heat and have all three. Bond on or use the demist vent screws to hold in place. No holes pre cut, put the tubing where you want it and install one defrost duct. Custom curved to fit the FFR car and fit between the dash and the firewall. Plenum is great for Air Conditioned cars with too much tubing already behind the dash.
