That is an interesting thought. My truck is also a single blade throttle; it causes me some difficulty when dawdling along on base (25 mph limits typically). I'm thinking a warm air intake will help this?
I like SH130; 80-85 mph is nice (except when the vehicle guzzles fuel at 15-16 mpg)

I'm not much of an engine guy.On my Honda, air temp is thermostatically controlled at about 100 F and fed to the carb.
On an EFI engine,if you were going to do this I'd think you'd want it upstream of the mass airflow sensor,or else the computer couldn't properly control the injectors.
But horsepower for horsepower,the engine would need the same mass of air,and you'd still be stuck with the inlet restriction of the barely-cracked throttle plate.
Mitsubishi and Toyota have GDI engines which are throttle-less,just like a Diesel,with 15% higher thermal efficiency because they're always at WOT.
I've heard of gasoline engines with dual throttles,one for low speed,then transitioning to the secondary for higher power settings.I've never seen one,but it sounds like a good compromise.
