any electronic hot air intakes?

I thought last night that a simple temp sensor controlling a servo motor connected to a flap, with a duct to the exhaust manifold could provide on demand hot air right from when the vehicle is turned on, and as the engine warmed and then the servo could close in varying degrees to keep the intake air at 140 or so. might be able to do it with a simple bi-metal thermostat too.

I remember some older cars having vacum controls for similar function, there was a a temp controlled vacuum switch in the air filter that could be used to pull a door open or closed as the engine warmed. I'm pretty sure I saw something on a big old carburated chev v8 caprice.

I was thinking electronic because with programmed slower reaction time it would not open and close every time you shift, I dont know, just an idea
