Sprint Replacement Filter

The Sprint Replacement Filter by KINSER AIR FILTERS is a foam air filter element engineered specifically for sprint car air box systems where maximum airflow and engine protection are non-negotiable. Built for competitive and recreational sprint car operators, this replacement filter maintains consistent air delivery under high-RPM conditions while trapping particulates that would otherwise compromise combustion efficiency and engine longevity. Whether you're running a precision sprint car engine or maintaining an existing system, this filter addresses the core challenge of balancing intake volume with contamination control in open-track environments.

Constructed from premium foam material, the Sprint Replacement Filter leverages the superior flow characteristics and reusable nature of foam media compared to traditional paper alternatives. Foam's cellular structure allows unrestricted airflow while capturing fine dust, pollen, and debris at the micron level—critical for sprint car engines operating at elevated boost levels and aggressive fuel maps. The filter's substantial 10.55 x 4.45 x 22.95-inch dimensions provide a large filtration surface area, reducing pressure drop across the intake tract and minimizing parasitic losses that would otherwise rob horsepower. At just 0.42 lbs, the lightweight design eliminates unnecessary mass in the engine bay, a consideration that matters in weight-sensitive competition environments.

Sprint car drivers and mechanics rely on this replacement element to maintain OEM air box performance during mid-season service intervals or after high-dust events. The foam construction allows for quick cleaning and re-oiling using standard filter maintenance products, extending service life and reducing consumable costs across a full race season. This filter is the direct replacement for KINSER sprint car air box assemblies (MPN 1001-F01), ensuring fitment certainty and eliminating guesswork during installation. Keep a spare on hand for race day peace of mind, or stock several for fleet maintenance across multiple cars.
