I appreciate your concern. by removing the little flap, I am allowing it to draw hot air from the manifold continually. I might go ahead and block off the main inlet ,and just feed it with the 1 3/8" hot air tube. I seldom, if ever rev it over 3000 rpm, so the loss of the 2" inlet tube probably won't hurt mpg. I could also run a hose down to the exhaust manifold, and have 2 warm air intakes.
