I changed my evaporator fan. I have a damaged flex duct that connects the fan shroud to the fixed duct going up to the dash. It measures 3.25 inches in Diameter,and about 3 inches long,can anyone help? I can not find anyplace not even at the Porsche dealer. Does not show up on the parts pages.

had the same problem. I fixed it using a flexible 1/8" thick rubber duct that was 4" diameter. Slice it down the center for ease of installation and to overlap and get the correct diameter. Or you could just get a 4" aluminum flex dryer vent and clamp it down to 3.25". I wanted a little more of an insulation factor for mine, which is why I used the 1/8" rubber. Don't fret, the old one had about a 0% insulation factor so as long as you get a sealed duct in there, your fine.

Try an aircraft supply shop.

Go down to line 13- AERODUCT TUBE SCAT-13 3-1/4ID

Not exactly cheap, but it'll work just fine.
