Sold as a pair, these upgraded air ducts are a great addition to the ventilation system on the pre-964 911. They allow directional control of cool air to your body but still allow hot air to go to your feet.  Each duct can be rotated so you can divert passenger side cooling to the driver side for increased comfort.

They can be used with the standard ventilation system or with our Electrocooler AC system. To install, simply remove the original under dash 'diffuser' and replace with our duct. 

Ducts are made from high temperature carbon fibre filled nylon.  They won't deform or melt with heat. Be sure to check the condition of your blend valve bases before purchasing.
