On race day, Greg Biffle dominated, leading 168 of the first 218 laps. Biffle won the previous year's spring race at California, finished second in the fall, and had won the Busch race the day before. Tony Stewart was the fastest Chevy in the early going. He overcame the car falling off the jack on a pit stop and an unscheduled stop for a flat tire to claw his way back among the leaders only to have an engine failure at lap 215, ending a string of 30 straight races without a DNF. Biffle continued up front until lap 226. He reported to the crew that his engine had lost a cylinder and a few laps later, he retired to the garage. This left Matt Kenseth to take the lead and only a late-race caution kept him from pulling away. Smoke and oil from the No. 4 car of Scott Wimmer brought out a yellow with three laps to go. Kenseth easily held off Jimmie Johnson in the green-white-checkered finish to earn his 11th career win.
