Air Cleaner Base 14in

The Allstar Performance Air Cleaner Base 14in (ALL25941) is a lightweight aluminum intake manifold component engineered for small-block engine builds and carburetor installations. Built to OEM specification with a 5-1/8 inch carburetor flange and dropped base design, this air cleaner base integrates cleanly into engine bay layouts where vertical clearance is limited. The natural finish aluminum construction provides corrosion resistance typical of performance-grade intake components while maintaining minimal weight that doesn't add unnecessary mass to the engine assembly.

At 14.45 inches in diameter and weighing just 1.14 lbs, this base accepts standard carburetor mounting hardware and filters without secondary machining or modifications. The 5-1/8 inch flange specification matches the most common carburetor bolt pattern used on street and strip engines, making this base a direct fit for rebuilt or upgraded carburetors. The dropped base design lowers the overall package height, a critical consideration in vehicles with tight hood clearance—particularly relevant for engine swaps, restorations, and high-performance applications where every inch of vertical space matters.

This component serves builders, engine shops, and serious engine enthusiasts assembling or refreshing small-block powerplants. Buyers working on street rods, classic muscle cars, and engine platform upgrades rely on Allstar Performance parts for their proven fitment and dimensional accuracy. The base is ordered as a single unit and integrates with standard air filter assemblies, making it a straightforward component in the intake assembly workflow.

Allstar Performance maintains a strong reputation in the engine building community for precision castings and finished components. This air cleaner base reflects that standard—a no-nonsense intake component that handles its single job without unnecessary complexity or material waste.
