I've read about cars during the 1950-60's national fuel economy runs using a warm air intake for increased mileage. Some of them seemed to be modified intake warmers used for carburetor de-icing. They also had a much more limited (and thus more controlled) ignition system.

There are engine modifications that can be done to lower the tendency of an engine to ping. One is to radius all the corners within the cylinder/piston cavity...something only practical during a rebuild, but useful nonetheless.
