Good point! there is also mpg to be gained for the daily driver and reduced lift and drag at higher speeds for the track guys.
One more thing to note it will increase air flow through the radiator and it will decrease air flow over the oil pan. The oil temps will go up about 10* in average driving on a 75* day. It shouldn't matter unless someone is really pushing the limits and it's nothing an oil cooler won't fix
