The NHRA season kicked off March 11-14 at the AMALIE Motor Oil NHRA Gatornationals at Gainesville Raceway in Gainesville, Florida. 


Josh Hart won the Top Fuel class, beating the odds by claiming a victory in his Top Fuel debut (he is a two-time U.S. Nationals Top Alcohol Dragster champion). Top Fuel dragsters are some of the fastest accelerating vehicles in the world, and feature 11,000-horsepower engines that can reach speeds of 330 mph, powered by a supercharged and fuel-injected 500-cubic-inch iteration of the Chrysler Hemi engine.


You don’t have to race in a Top Fuel dragster to enjoy the horsepower benefits of K&N intakes and filters. K&N has been designing intakes for Hemi engines for years, and has one of the most robust product ranges on the market. Check out estimated horsepower gains in the dropdown below.
