K&N Horsepower Challenge
The lucrative K&N Horsepower Challenge is a special race-within-a-race bonus event highlighting the top seven Pro Stock drivers who have accumulated the most qualifying points during NHRA Mello Yello Drag Racing Series events. An eighth driver is decided by a special fan vote on the K&N website.
Drivers began earning points for the 2018 K&N Horsepower Challenge at the 2017 Denso Spark Plugs NHRA Nationals in Las Vegas and continue to earn through the 2018 Amalie Motor Oil NHRA Gatornationals. The top seven drivers in points clinch a spot in the challenge, while the eighth spot is voted by fans.
The winner of the K&N Horsepower Challenge earns $50,000, and the runner- up receives $10,000. The two semifinalists take home $3,000 each, and the four first-round finishers earn $2,500 each. In addition, the No. 1 qualifier at each NHRA Mello Yello Drag Racing Series event is awarded a $3,000 bonus.
The 2017 installment of the annual event featured Jason Line, Greg Anderson, Bo Butner, Shane Gray, Vincent Nobile, Drew Skillman, Allen Johnson, and Chris McGaha.
