put a little air scoop under the car to direct are onto the empeg

I don't think the empeg is built for water cooling by flooding

Seriously though, I had the MkI for more than a year in the same car without any problem. It's been quite hot sometimes, especially after long drives in hot & sunny weather (not all that common here though )
Now, seeing a temp readout, we have gotten something new to worry about...

As to Home Depot, that'd be a long trip as I'm in Sweden
But I did play with the thought of adding some alu flex tubing to redirect a bit of the AC'd air to the empeg. But the interior of the dash isn't exactly spacious, so getting it even close would be very hard. Will have to settle for running the cold air through the center vents...
