The 2005 O'Reilly Challenge was a Busch Series event held at Texas Motor Speedway on November 5, 2005. Kevin Harvick won his fourth and final event of the year, holding off Greg Biffle. It was an emotion win for Harvick, who dedicated the win to his father-in-law John Linville, who passed during the week. It was also a good day for Martin Truex, Jr. His 11th place finish protected an 84-point championship lead on Clint Bowyer (7th). Stats
