Flat Front Air Box

The Flat Front Air Box by Allstar Performance is designed for engine builders and street/strip enthusiasts who require precise air intake management. This component is essential for high-performance builds, as it effectively controls air velocity and distribution into the carburetor while ensuring clean and undisturbed flow patterns. It is suitable for both naturally aspirated small-block and big-block platforms.

The flat front design integrates seamlessly into existing hood and firewall configurations without extensive fabrication. It features a controlled plenum that minimizes turbulent air entry and stabilizes fuel atomization at the carburetor inlet. The all-steel construction weighs 2.16 lbs, providing rigid support without adding unnecessary weight, while the dimensions of 10.65 x 2.85 x 22.65 inches make it ideal for tight engine compartments.

This air box is particularly beneficial for tuners who need predictable baseline conditions before making adjustments to jetting or fuel pressure. It works best on carbureted platforms with single or dual four-barrel configurations, where stable, cool air delivery is crucial for performance. The design prioritizes repeatability and consistency, making it a valuable addition to any performance build.
