14in x 3in Round Air Filter

The 14in x 3in Round Air Filter by SPECTRE is a premium intake component designed for vehicle enthusiasts and mechanics who seek 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 actual dimensions of 14.5 inches in diameter and 3.5 inches in 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, ensuring that performance is not sacrificed for looks. With its effective design and compatibility with a range of vehicles, this air filter is an excellent choice for enhancing engine performance.
