14in x 3in Round Air Filter

The 14in x 3in Round Air Filter by SPECTRE is a premium intake component engineered for vehicle enthusiasts and mechanics seeking reliable engine protection and improved airflow. This classic round filter design has been a staple in performance and restoration builds for decades, offering simplicity and effectiveness where it matters most. Whether you're running a carbureted classic, a vintage muscle car, or a custom hot rod, this filter addresses the critical need for clean combustion air while maintaining aesthetic appeal under the hood.

SPECTRE's design utilizes a robust pleated media construction that balances filtration efficiency with minimal restriction—essential for naturally aspirated engines where intake velocity directly impacts volumetric efficiency. The 14-inch diameter and 3-inch height create substantial filter area, reducing pressure drop across the element and extending service intervals compared to smaller alternatives. The round housing accommodates universal mounting applications, making installation straightforward on custom intake manifolds, velocity stacks, and traditional air cleaner assemblies without requiring complex fabrication or adapter plates.

Builders and restorers benefit most from this filter when constructing carbureted systems, vintage street machines, or any application where traditional round air cleaners are preferred over modern sealed box designs. Mechanics frequently specify this component when clients demand original-style aesthetics combined with modern filtration reliability. Compatibility spans most domestic and imported classics from the 1960s through early 1990s equipped with standard air cleaner bowls; verify your specific mounting flange diameter and carburetor opening before ordering to ensure proper fit and seal.
