Walker Performance Sprint Car Air Box Carbon Fiber Base/Clips Kit

Built to withstand the harshest racing conditions, a complete Walker Performance Filtration sprint car air box setup built to keep airflow strong and filtration tight in dusty, abusive track conditions. At the foundation is the 300853 carbon fiber air box base in a rectangular footprint (19" L x 13.8125" W), giving you a lightweight, rigid platform that fits common sprint car packaging and helps keep the assembly stable.

To lock everything together, the kit includes Walker air box clips (94030107)—a 6-pack of spring clip clamps designed to clamp the filter, base, and lid tightly. These plastic clips are engineered for strong spring pressure while staying lighter than typical steel clips, helping compress the lid-to-base seal for an airtight fit and reducing the chance of dirt sneaking past the edge during a race.

Rounding it out is the 94030902 Economy Air Filter Box Replacement, a washable, reusable “red box” style replacement built from rigid foam to keep weight and cost down. With filtration through the top and around the sides, it’s designed to protect your engine from dust and debris without sacrificing airflow—so you can focus on making laps, not cleaning up dirt ingestion.
