I made a very workable valve for my cabin air inlet out of a 4" plastic slide 
valve used to shut off sawdust collector vacuums, as sold by Builder's 
Square. They also sell larger ones I think.

Now in the Winter, I can shut off the cold Northern Illinois air by pulling 
on a cable attached to the slide valve.

I am thinking of electrifying it.  It is fully adjustable for all different 
temperature ranges.  

It is injection molded, however, and my not stand  up to engine temps.  But, 
I saw a similar valve (for sewer shutoff) in an RV (rec vehicle) parts store 
that was more substantial which may work in inlet cooling plenums.
