Small Ribbed Oval Air Cleaner

The Billet Specialties Small Ribbed Oval Air Cleaner (SKU BSP15630) is a premium intake solution designed for street rods, custom hot rods, and classic muscle car builds where appearance and performance are essential. This finned aluminum assembly delivers a polished aesthetic that enhances show-quality engine bays, while the raised base design ensures compatibility with modern EFI systems and tight underhood configurations.

Built for carburetors with a 5-1/8 inch flange opening, this air cleaner assembly combines form with purposeful engineering. The ribbed oval design increases effective filtration surface area, and the polished aluminum construction resists corrosion, maintaining its mirror finish through seasons of use. The finned exterior helps accelerate air cooling as it enters the carburetor, supporting consistent fuel atomization and improving throttle response on naturally aspirated engines.

This oval air cleaner is particularly beneficial in applications where traditional round assemblies cannot fit or visually integrate with custom engine setups. Weighing just 5.73 pounds, the lightweight aluminum construction minimizes parasitic weight without sacrificing structural rigidity or durability in high-vibration environments.
