Air Cleaner Bottom 14in

The Air Cleaner Bottom 14in from ALLSTAR PERFORMANCE is a precision-engineered intake component designed for street and competition engine builders who demand reliable filtration support. This aluminum base serves as the foundation for a complete air intake system, providing a stable platform that positions your carburetor at the optimal angle while maintaining clean airflow into the engine. Whether you're building a carbureted V8, restoring a classic muscle car, or fabricating a custom hot rod, this 14-inch round air cleaner base addresses a critical need: securing the filter assembly while managing intake geometry for maximum efficiency.

Machined from lightweight aluminum in a natural finish, the Air Cleaner Bottom 14in features a dropped base design that lowers the filter assembly relative to the carburetor mounting surface—a geometry choice that improves hood clearance and allows for larger filter media without interference. The 5-1/8-inch carburetor flange ensures a secure, repeatable interface with standard carb studs, while the 14-inch diameter accommodates full-flow filter elements common in high-performance and street applications. At just 1.08 lbs, the aluminum construction contributes negligible weight to your engine bay while delivering the rigidity needed to isolate vibration and prevent seal degradation during sustained operation or spirited driving.

Technicians and enthusiasts building carbureted engines will find this base compatible with any intake setup using a 14-inch round filter housing and a standard 5-1/8-inch carb mounting flange. The dropped base design is particularly valuable in tight engine compartments where hood clearance is limited, and in custom applications where you need precise vertical stack height for belt-driven accessory alignment. Installation is straightforward: bolt the base to your carburetor studs, seat your filter media, and secure the top cap—no special tools or machine work required. This component is essential for anyone transitioning from a stock flat-base setup to a performance air intake or restoring an original appearance while upgrading filtration capacity.
