NASCAR Increases Inlet Openings For Daytona 500
NASCAR announced a rule change for the Daytona 500 at Daytona International Speedway on Sunday. Because the weather forecast Sunday calls for warmer temperatures, the sanctioning body changed the air inlet opening from 2 1/2 x 20 inches to 3 x 20 inches. This will give teams more air to cool their engines.
