After a surprising finish at Daytona, Dale Earnhardt Jr. is back in the studio to catch up on the latest racing headlines on this week’s edition of Dirty Air. It's a star-studded lineup on the show this week, with Bubba Wallace, Harrison Burton and Jeff Burton all jumping on the show. 

Harrison Burton’s unpredictable win means the Playoffs cutline moved again, and several drivers face a must-win situation rolling into Darlington:

• Harrison wins number 100 for the legendary Wood Brothers
• “Winning the lottery” is a good thing for smaller teams
• Was Parker Retzlaff in the wrong?
• Bubba Wallace stops by the studio
• The Playoff bubble shifts again
• NASCAR returns to Mexico City in 2025
