I have to offer an "air-condition" for cold days.
The air from the motor keeps the legs of the driver warm.
I used it since 35000 km without any thermic problems.
To built it in, you need about 1,5 hours. I ordered some hundred of these "air conditions".
I can send some other jpg-files of the built-in-instructions.
The price: about 40 US.
