Air Box 2BBL Standard Fiberglass

The FIVESTAR Air Box 2BBL Standard Fiberglass is a composite cowl induction air intake assembly engineered for 2-barrel carburetor engines. This fiberglass construction air box delivers improved air flow characteristics compared to standard plastic housings, making it the choice for builders focused on intake efficiency and clean engine bay aesthetics. The white composite finish resists UV degradation and provides long-term durability in both street and performance applications.

Built to specification with dimensions of 22.25 x 7.25 x 31.75 inches and weighing just 5.4 lbs, this air box integrates the cowl induction design principle—drawing cooler air from the hood's base to the carburetor inlet. The fiberglass composite material provides structural rigidity while maintaining a lightweight profile, critical for engines where intake temperature and manifold pressure directly affect fuel atomization and combustion efficiency. The 2-barrel configuration ensures compatibility with standard dual-throat carburetor setups common in classic American V8 and inline engines from the 1960s through 1980s.

This assembly suits restoration projects, street rods, classic truck builds, and performance engines where OEM air box replacement is required. Builders upgrading from worn or cracked plastic housings will appreciate the durability of composite fiberglass construction. The standard sizing ensures drop-in compatibility with original carburetor mounts and engine bay clearances on vehicles originally equipped with similar 2-barrel systems. Installation as part of a complete intake kit streamlines the build process and maintains engine compartment organization.

FIVESTAR components are recognized in the restoration and performance engine community for attention to original-style design married with modern manufacturing standards. The white composite finish complements popular engine dress-up and detailing approaches, particularly in vehicles with factory or custom engine bay work.
