Air Cleaner Kit 15in X 2in Oval Half Finned Top

The Specialty Products Company Air Cleaner Kit with 15-inch Oval Half Finned Top (Model 6491BK) is a high-flow intake assembly designed for marine carburetor applications requiring reliable air filtration in saltwater and freshwater environments. This half-finned air cleaner delivers superior cooling and airflow compared to traditional sealed designs, making it the choice for boaters who demand consistent engine performance in extended duty cycles.

The kit features a 2-inch element depth paired with a 5-1/8-inch carburetor flange, engineered to accommodate a wide range of marine powerplants without requiring adapter rings. The finned design increases surface area for cooling and airflow efficiency—critical in marine service where engine compartments can reach high temperatures during sustained operation. The aluminum construction with black powder-coat finish resists corrosion from salt spray and moisture, extending service life in harsh offshore conditions. The flat base design provides straightforward mounting to standard marine carburetor flanges.

This assembly suits weekend fishermen upgrading tired original equipment, serious offshore anglers running long duty days, and marine mechanics maintaining charter and commercial vessels. The complete kit format eliminates the need to source multiple components separately, reducing downtime during maintenance or engine rebuilds. For operators restoring vintage marine engines or seeking improved intake flow in performance applications, the half-finned design balances authentic appearance with functional cooling advantages.

Marine air cleaner assemblies are critical to carburetor longevity and consistent fuel economy. A properly specified intake protects internal carburetor passages from water intrusion and salt contamination while maintaining the air-fuel ratio your engine was tuned to deliver. Verify your current carburetor flange diameter and element compatibility before ordering to ensure seamless installation.
