Fast reacting IAT sensor replaces stock sensor

The sensor responds pretty much immediately. If you aren't seeing quick changes in air temperature readings it's probably because the air temperature isn't changing rapidly, at least from where the sensor is reading it. In my bench testing just breathing hot air on it caused rapid changes in resistance. You might also make sure the sensor is clocked properly so the air flows through the plastic square area rather then into it. Not sure if it makes a huge difference or not but maybe.
