[QUOTE="UselessPickles, post: 556660, member: 3256"] Colder air with proper fueling requires smaller throttle openings to maintain speed. Smaller throttle openings causes more turbulence in the incoming air and somehow mixes/burns less efficiently, causing you to need to open the throttle just a little bit more to use more air and fuel at the lower efficiency to maintain speed as compared to if the air was warmer. Some cars run the engine coolant through the air box to warm the air and improve mileage at the loss of maximum available power. [/QUOTE]
