NHRA Introduces Innovative Air Intake System for Pro Stock Class
March 8, 2025
The National Hot Rod Association (NHRA) has unveiled a groundbreaking air intake system for its Pro Stock category, developed in collaboration with K&N Engineering. This initiative aims to modernize the Pro Stock class by integrating advanced electronic fuel injection (EFI) systems and eliminating traditional hood scoops.
The newly designed air intake system features a carbon fiber construction, engineered to channel ambient air from a discreet opening in the lower grille directly into the 500 cubic-inch, naturally aspirated engines. This design not only enhances aerodynamic efficiency but also aligns with the NHRA’s objective to make Pro Stock vehicles more representative of modern automotive aesthetics.
Rick Jones of RJ Race Cars, who played a pivotal role in the system’s development, expressed enthusiasm about the collaboration: “It was no easy task to accomplish in just a couple short months, but we had the privilege of working together with Tim White, Glenn Gray, and Bob Blackwell from NHRA, along with Steve Williams and Jonathan Fiello from K&N, during the development and design of this system.”
The transition to EFI systems represents a significant shift from the carbureted setups previously used in Pro Stock racing. The NHRA has partnered with Holley to implement a standardized EFI package, incorporating components like the Holley HP EFI system and 160-lb/hr injectors. This move is expected to enhance engine performance and reliability, bringing Pro Stock technology in line with contemporary automotive standards.
The introduction of this innovative air intake system and the shift to EFI are part of the NHRA’s broader strategy to rejuvenate interest in the Pro Stock class. By adopting modern technologies and design elements, the NHRA aims to attract a new generation of fans and participants to the sport.
As the 2025 season unfolds, teams are actively integrating these advancements into their vehicles, with the racing community eagerly anticipating the impact on competition dynamics and performance metrics.
