Fan participation, including eight trips to the program finals in Las Vegas and a grand prize of a new Toyota Tacoma, highlight the 29th annual K&N Horsepower Challenge Sweepstakes.
In addition to potentially winning a tremendous prize package including the custom Toyota Tacoma, fans will again be able to vote for their favorite National Hot Rod Association Pro Stock driver as the eighth and final participant in the 2013 event, which will be held April 6 on the Strip at Las Vegas Motor Speedway.
