Sprint Car Air Filter Only 6.25in

The K&N Engineering Sprint Car Air Filter Only 6.25in (MPN 100-8564) is a replacement high-flow air filter element engineered specifically for sprint car racing applications where unrestricted airflow directly impacts engine performance. Built for serious competitors and racing teams, this filter works as the core component of a custom racing air box assembly, delivering the filtration efficiency and air delivery demanded by high-RPM competition engines. Sprint car racing requires precision air intake management, and K&N's design addresses this by providing maximum flow capacity while maintaining effective particle separation.

This sprint car air filter is constructed from K&N's signature oiled composite media, a reusable design that captures contaminants while allowing superior air passage compared to standard disposable filters. The 6.25-inch tall filter element is sized to fit within racing air box configurations measuring 18.906 x 13.75 inches, optimizing the balance between intake volume and underhood packaging constraints. The oiled filter technology traps particles on contact while the multi-layer composite construction resists dust bypass, ensuring consistent engine protection across extended race sessions. Unlike paper filters that degrade over time, this reusable element can be cleaned and re-oiled between events, making it both economical and environmentally practical for racing operations.

Racers selecting the Sprint Car Air Filter Only 6.25in should verify compatibility with their existing air box assembly, as this replacement element fits specifically within K&N sprint car air box kits and similarly dimensioned custom intake manifolds. Installation requires positioning the filter element within the air box housing and securing according to the manufacturer's mounting specifications—no special tools are required. Teams operating fuel-injected or carbureted sprint cars benefit from this filter's reliability under high-load conditions, whether competing in winged or non-winged sprint car formats. For drivers seeking to upgrade their existing air intake system, this filter represents a direct path to improved throttle response and consistent power delivery across the RPM band.
