Rule-breaking tactics, however, swirled around the qualifying. Five teams were slapped with suspensions, fines and points deductions for illegal modifications. The hardest hit was Michael Waltrip, whose No. 55 team was the most harshly punished, having their race director and crew chief suspended indefinitely, fined $100,000 (US) and the docking of 100 owners and drivers points for a gelatin-like substance found in the intake manifold during inspections before the qualifying, and in a replacement manifold after qualifying. The substance was revealed by NASCAR, during the announcement of the penalties, to be an unspecified oxygenate compound that was blended with the fuel, possibly in an attempt to defeat the effect of the restrictor plate. Waltrip fired said crew chief for the unauthorized change that neither he or anyone else authorized. The No. 17 Matt Kenseth team of Roush Racing and the No. 9 Kasey Kahne team from Evernham Motorsports had their crew chiefs suspended for the first four races, fined $50,000 and had 50 driver and owner points taken away for illegal modifications discovered in post-qualifying inspections. All three teams also had their qualifying times for the pole positions disqualified, and Waltrip's original car was impounded by NASCAR, forcing him to go to a back-up auto for the first qualifying race.
