These were aftermarket accessories sold for a few years.  I actually 
had a pair in my hands around 1970, but they did not fit the louvers 
of the T3 that I had at that time.  They were made because Vw changed 
the way that the louvers faced and there was a perceived increase in 
engine temp.  It is not clear whether this perceived increase was 
real or not.

It's not clear, there is no data.

Use the right timing and fuel/air mixture.  Make sure that ALL the 
original cooling tin (and intake air bellows!) and thermostat system 
is installed and properly adjusted.  Under these conditions, it your 
engine is stock displacement, or only slightly enlarged, you will 
never have any trouble.

The most common cause of overheating is cooling parts left out
and tune-up specs that have been altered or ignored.

There is none.  This was never an official VW or VWoA part.
