It will just decrease your gas mileage and probably your HP. Don't bother.
I agree. However if you need to remove your IAT sensor for say, turbo, the resistor trick isn't a terrible idea. Also it eliminates fuel fluctuation based off of IAT readings. What you do is look at the helms manual, it will show the resistance/temperature curve of the sensor, and you chose a resistor for some middle value, say 80 deg Fahrenheit...
