    Hey guys,

    Curiosity here. Saw these on a euro car posted online and was wondering if anyone knows where/how they connect and what they are for. My assumption is cabin air flow but I have 0 idea. My car us with my mechanic but I'm nearly positive mine doesn't have these (series 1 us car)

    IIRC, they were on the earliest cars but discontinued fairly quickly.

    Looks like 74 euro only from what pics I can find. Any idea what they were used for?

    Just cabin ventilation I believe. 911s had them through into the ‘80’s.

    My question is where they hook up in the interior. In the 993s and the like that had this they had internal vents behind the rear seats iirc. I cant picture where these would hook up in a gt4

    I doubt they ""connect" anywhere. Pop out the rear most interior panel with the dome light and see.

    There is no space for any ducts. Nor any parts in the Parts Catalogue

    I wonder if the idea was that the pleats in the headlining created small gaps around the cover above the rear window, to allow cabin air to reach the vents?

    Then Ferrari discovered it didn't really work, and so dropped the idea?

    There is enough air leaks in these cars no vents needed

    That..... honestly feels way too complex for ferrari in the 70s if I'm honest. I'm more inclined to believe they got a shipment of bodies that had them and just couldn't be bothered to send them back than I am that they thought they woukd get airflow through the headliner stitching...

    The styling clay had far more slots in, you would not do it if required as it adds tooling complexity piercing these.

    The original clay model had 10 slots.

    They were an originally planned design feature - Not a manufacturing error: https://www.pistonheads.com/gassing/topic.asp?h=0&t=1747385

    Yes instead of making front vent windows that opened or redirecting the front radiator grill heat they made some slots. The car is really really hot inside over 72 deg F
