14in Flat Bottom A/C

The MOROSO 14in Flat Bottom A/C air cleaner assembly delivers street-proven performance for carbureted engine builds seeking reliable filtration with classic styling. This 14-inch round air cleaner kit features a 3-inch filter element and accommodates a 5-1/8-inch carburetor flange, making it compatible with a wide range of small-block and big-block engine platforms common in street rods, muscle cars, and custom hot rods. The flat base design provides a clean mounting surface without obstruction, and the polished chrome finish adds visual appeal to engine bays where aesthetics matter as much as function.

Built from steel construction, the MOROSO 65911 air cleaner assembly withstands heat cycling and engine bay vibration over extended use. The 3-inch depth element design balances airflow capacity with compact footprint, critical for engine compartments where hood clearance is limited. The 5-1/8-inch carb flange measurement ensures proper sealing and consistent air delivery to the carburetor's intake venturi. At 5.06 pounds, this assembly adds negligible weight while maintaining structural rigidity—important for street and strip applications where engine bay integrity affects overall vehicle dynamics.

This air cleaner suits builders and enthusiasts restoring or modifying carbureted engines who prioritize both performance filtration and traditional appearance. The flat-bottom configuration works with popular intake manifold and carburetor combinations, making it a straightforward bolt-on upgrade for vehicles running four-barrel carburetors in the mid-range displacement category. Chrome finish resists corrosion in varied storage and display conditions, though periodic cleaning maintains the polish. The kit arrives complete and ready to install without additional components or adapters for standard applications.
